[0002] This invention relates to novel supported catalyst compounds comprising group 4 bis(phenolate) complexes, catalyst systems comprising such, and uses thereof.

BACKGROUND OF THE INVENTION

[0003] Olefin polymerization catalysts are of great use in industry. Hence there is interest in finding new catalyst systems that increase the commercial usefulness of the catalyst and allow the production of polymers having improved properties.

[0004] Catalysts for olefin polymerization can be based on bis(phenolate) complexes as catalyst precursors, which are activated typically by an alumoxane or an activator containing a non-coordinating anion.

[0011] New supported catalysts capable of polymerizing olefins to yield high molecular weight and/or high tacticity polymers in gas-phase and/or slurry polymerization processes are desirable for the industrial production of polyolefins. There is still a need in the art for new and improved supported catalyst systems for the polymerization of olefins, in order to achieve specific polymer properties, such as high molecular weight and/or high tacticity polymers, preferably using gas-phase and/or slurry processes.

[0012] It is therefore an object of the present invention to provide novel supported catalyst compounds, catalysts systems comprising such compounds, and processes for the polymerization of olefins using such compounds and systems.

Definitions

[0016] For the purposes of this invention and the claims thereto, the following definitions shall be used:

[0017] The new numbering scheme for the Periodic Table Groups is used as described in Chemical and Engineering News , v.63(5), pg. 27 (1985). Therefore, a“group 4 metal” is an element from group 4 of the Periodic Table, e.g. Hf, Ti, or Zr.

[0018] “Catalyst productivity” is a measure of the mass of polymer produced using a known quantity of supported polymerization catalyst per unit time. Typically, “catalyst productivity” is expressed in units of (g of polymer)/(g of supported catalyst)/hour. If units are not specified then the“catalyst productivity” is in units of (g of polymer)/(grams of supported catalyst)/hour.

[0019] "Conversion" is the percentage of a monomer that is converted to polymer product in a polymerization, and is reported as % and is calculated based on the polymer yield, the polymer composition, and the amount of monomer fed into the reactor.

[0020] An“olefin,” alternatively referred to as“alkene,” is a linear, branched, or cyclic compound of carbon and hydrogen having at least one double bond. For purposes of this specification and the claims appended thereto, when a polymer or copolymer is referred to as comprising an olefin, the olefin present in such polymer or copolymer is the polymerized form of the olefin. For example, when a copolymer is said to have an "ethylene" content of 35 wt% to 55 wt%, it is understood that the mer unit in the copolymer is derived from ethylene in the polymerization reaction and said derived units are present at 35 wt% to 55 wt%, based upon the weight of the copolymer. A“polymer” has two or more of the same or different mer units. A“homopolymer” is a polymer having mer units that are the same. A“copolymer” is a polymer having two or more mer units that are different from each other. A“terpolymer” is a polymer having three mer units that are different from each other. Accordingly, the definition of copolymer, as used herein, includes terpolymers and the like.“Different” as used to refer to mer units indicates that the mer units differ from each other by at least one atom or are different isomerically. An "ethylene polymer" or "ethylene copolymer" is a polymer or copolymer comprising at least 50 mole% ethylene derived units, a "propylene polymer" or "propylene copolymer" is a polymer or copolymer comprising at least 50 mole% propylene derived units, and so on.

[0021] Ethylene shall be considered an a-olefin.

[0022] Unless otherwise specified, the term“C _n ” means hydrocarbon(s) having n carbon atom(s) per molecule, wherein n is a positive integer.

[0023] The term“hydrocarbon” means a class of compounds containing hydrogen bound to carbon, and encompasses (i) saturated hydrocarbon compounds, (ii) unsaturated hydrocarbon compounds, and (iii) mixtures of hydrocarbon compounds (saturated and/or unsaturated), including mixtures of hydrocarbon compounds having different values of n. Likewise, a“C _m -C _y ” group or compound refers to a group or compound comprising carbon atoms at a total number thereof in the range from m to y. Thus, a C ₁ -C ₅₀ alkyl group refers to an alkyl group comprising carbon atoms at a total number thereof in the range from 1 to 50.

[0024] The terms“group,”“radical,” and“substituent” may be used interchangeably.

[0025] The terms“hydrocarbyl radical,”“hydrocarbyl group,” or“hydrocarbyl” may be used interchangeably and are defined to mean a group consisting of hydrogen and carbon atoms only. Preferred hydrocarbyls are C1-C100 radicals that may be linear, branched, or cyclic, and when cyclic, aromatic or non-aromatic. Examples of such radicals include, but are not limited to, alkyl groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert- butyl, pentyl, iso-amyl, hexyl, octyl cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclooctyl, and the like, aryl groups, such as phenyl, benzyl naphthalenyl, and the like. [0026] Unless otherwise indicated, (e.g., the definition of "substituted hydrocarbyl", etc.), the term“substituted” means that at least one hydrogen atom has been replaced with at least one non-hydrogen group, such as a hydrocarbyl group, a heteroatom or heteroatom-containing group, such as halogen (such as Br, Cl, F or I) or at least one functional group such as -NR*2, -OR*, -SeR*, -TeR*, -PR* ₂ , -AsR* ₂ , -SbR* ₂ , -SR*, -BR* ₂ , -SiR* ₃ , -GeR* ₃ , -SnR* ₃ , -PbR* ₃ , -(CH2)q-SiR* ₃ , and the like, where q is 1 to 10 and each R* is independently hydrogen, a hydrocarbyl or halocarbyl radical, and two or more R* may j oin together to form a substituted or unsubstituted completely saturated, partially unsaturated, or aromatic cyclic or polycyclic ring structure), or where at least one heteroatom has been inserted within a hydrocarbyl ring.

[0027] The term "substituted hydrocarbyl" means a hydrocarbyl radical in which at least one hydrogen atom of the hydrocarbyl radical has been substituted with at least one heteroatom (such as halogen, e.g., Br, Cl, F or I) or heteroatom-containing group (such as a functional group, e.g., -NR*2, -OR*, -SeR*, -TeR*, -PR* ₂ , -AsR* ₂ , -SbR* ₂ , -SR*, -BR* ₂ , -SiR* ₃ , -GeR* ₃ , -SnR* ₃ , -PbR* ₃ , -(CH2)q-SiR* ₃ , and the like, where q is 1 to 10 and each R* is independently hydrogen, a hydrocarbyl or halocarbyl radical, and two or more R* may join together to form a substituted or unsubstituted completely saturated, partially unsaturated, or aromatic cyclic or polycyclic ring structure), or where at least one heteroatom has been inserted within a hydrocarbyl ring.

[0028] The term "aryl" or "aryl group" means an aromatic ring (typically made of 6 carbon atoms) and the substituted variants thereof, such as phenyl, 2-methyl-phenyl, xylyl, 4-bromo- xylyl. Likewise, heteroaryl means an aryl group where a ring carbon atom (or two or three ring carbon atoms) has been replaced with a heteroatom, such as N, O, or S. As used herein, the term "aromatic" also refers to pseudoaromatic heterocycles which are heterocyclic substituents that have similar properties and structures (nearly planar) to aromatic heterocyclic ligands, but are not by definition aromatic.

[0029] The term "substituted aromatic," means an aromatic group having 1 or more hydrogen groups replaced by a hydrocarbyl, substituted hydrocarbyl, heteroatom or heteroatom containing group.

[0030] A "substituted phenolate" is a phenolate group where at least one, two, three, four or five hydrogen atoms in the 2, 3, 4, 5, and/or 6 positions has been replaced with at least one non-hydrogen group, such as a hydrocarbyl group, a heteroatom or heteroatom-containing group, such as halogen (such as Br, Cl, F or I) or at least one functional group such as -NR* ₂ , -OR*, -SeR*, -TeR*, -PR* ₂ , -AsR* ₂ , -SbR* ₂ , -SR*, -BR* ₂ , -SiR* ₃ , -GeR* ₃ , -SnR* ₃ , -PbR*3, -(CH2)q-SiR*3, and the like, where q is 1 to 10 and each R* is independently hydrogen, a hydrocarbyl or halocarbyl radical, and two or more R* may j oin together to form a substituted or unsubstituted completely saturated, partially unsaturated, or aromatic cyclic or polycyclic ring structure), where the 1 position is the phenolate group (Ph-O, Ph-S-, and Ph-N(R )- groups, where R ^L is hydrogen, C ₁ -C ₄₀ hydrocarbyl, C ₁ -C ₄₀ substituted hydrocarbyl, a heteroatom or a heteroatom-containing group). Preferably, a "substituted phenolate" group in the catalyst compounds described herein is represented by the formula:

where R ¹⁸ is hydrogen, C ₁ -C ₄₀ hydrocarbyl (such as C ₁ -C ₄₀ alkyl) or C ₁ -C ₄₀ substituted hydrocarbyl, a heteroatom or a heteroatom-containing group, E ¹⁷ is oxygen, sulfur, or NR ¹⁷ , and each of R ¹⁷ , R ¹⁹ , R ²⁰ , and R ²¹ is independently selected fromhydrogen, C ₁ -C ₄₀ hydrocarbyl (such as C ₁ -C ₄₀ alkyl) or C ₁ -C ₄₀ substituted hydrocarbyl, a heteroatom or a heteroatom- containing group, or two or more of R ¹⁸ , R ¹⁹ , R ²⁰ , and R ²¹ are joined together to form a C ₄ -C ₆₂ cyclic or polycyclic ring structure, or a combination thereof, and the wavy lines show where the substituted phenolate group forms bonds to the rest of the catalyst compound.

[0031] An "alkyl substituted phenolate" is a phenolate group where at least one, two, three, four or five hydrogen atoms in the 2, 3, 4, 5, and/or 6 positions has been replaced with at least one alkyl group, such as a C ₁ to C ₄₀ , alternately C ₂ to C ₂₀ , alternately C ₃ to C ₁₂ alkyl, such as methyl, ethyl, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl, iso-amyl, hexyl, octyl cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclooctyl, adamantanyl and the like including their substituted analogues.

[0033] The term "ring atom" means an atom that is part of a cyclic ring structure. By this definition, a benzyl group has six ring atoms and tetrahydrofuran has 5 ring atoms.

[0034] A heterocyclic ring, also referred to as a heterocyclic, is a ring having a heteroatom in the ring structure as opposed to a“heteroatom-substituted ring” where a hydrogen on a ring atom is replaced with a heteroatom. For example, tetrahydrofuran is a heterocyclic ring and 4-N,N-dimethylamino-phenyl is a heteroatom substituted ring.

Examples of tertiary hydrocarbyl groups include tert-butyl, 2-methylbutan-2-yl, 2-methylhexan-2-yl, 2-phenylpropan-2-yl, 2-cyclohexylpropan-2-yl, 1-methylcyclohexyl, 1-adamantyl, bicyclo[2.2.1]heptan-l-yl and the like. Tertiary hydrocarbyl groups can be illustrated by formula A: , wherein R ^A , R ^B and R ^c are hydrocarbyl groups or substituted hydrocarbyl groups that may optionally be bonded to one another, and the wavy line shows where the tertiary hydrocarbyl group forms bonds to other groups.

[0038] A cyclic tertiary hydrocarbyl group is defined as a tertiary hydrocarbyl group that forms at least one alicyclic (non-aromatic) ring. Cyclic tertiary hydrocarbyl groups are also referred to as alicyclic tertiary hydrocarbyl groups. When the hydrocarbyl group is an alkyl group, cyclic tertiary hydrocarbyl groups are also referred to as cyclic tertiary alkyl groups or alicyclic tertiary alkyl groups. Examples of cyclic tertiary hydrocarbyl groups include 1-adamantanyl, 1-methylcyclohexyl, 1-methylcyclopentyl, 1-methylcyclooctyl, 1-methylcyclodecyl, 1-methylcyclododecyl, bicyclo[3.3.1]nonan-l-yl, bicyclo[2.2.1]heptan- 1-yl, bicyclo[2.3.3]hexan-l-yl, bicycle[l. l. l]pentan-l-yl, bicycle[2.2.2]octan-l-yl, and the like.

[0041] Where isomers of a named alkyl, alkenyl, alkoxide, or aryl group exist (e.g., n-butyl, iso-butyl, sec-butyl, and tert-butyl) reference to one member of the group (e.g., n-butyl) shall expressly disclose the remaining isomers (e.g., iso-butyl, sec-butyl, and tert-butyl) in the family. Likewise, reference to an alkyl, alkenyl, alkoxide, or aryl group without specifying a particular isomer (e.g., butyl) expressly discloses all isomers (e.g., n-butyl, iso-butyl, sec-butyl, and tertbutyl).

[0044] A“catalyst system” is a combination of at least one catalyst compound, at least one activator, and an optional support material. When "catalyst system" is used to describe such a pair before activation, it means the unactivated catalyst complex (precatalyst) together with an activator and, optionally, a co-activator. When it is used to describe such a pair after activation, it means the activated complex and the activator or other charge-balancing moiety. The transition metal compound may be neutral as in a precatalyst, or a charged species with a counter ion as in an activated catalyst system. For the purposes of this invention and the claims thereto, when catalyst systems are described as comprising neutral stable forms of the components, it is well understood by one of ordinary skill in the art, that the ionic form of the component is the form that reacts with the monomers to produce polymers.

DFTATLFn DESCRIPTION

[0049] This invention relates to a new catalyst family comprising transition metal complexes of a dianionic, tridentate ligand that features a central neutral donor group and two phenolate donors, where the tridentate ligands coordinate to the metal center to form two eight- membered rings. In complexes of this type it is advantageous for the central neutral donor to be a heterocyclic group. It is particularly advantageous for the heterocyclic group to lack hydrogens in the position alpha to the heteroatom. In complexes of this type it is also advantageous for the phenolates to be substituted with one or more cyclic tertiary alkyl substituents. The use of cyclic tertiary alkyl substituted phenolates is demonstrated to improve the ability of these catalysts to produce high molecular weight polymer.

[0050] Complexes of substituted bis(phenolate) ligands (such as adamantanyl-substituted bis(phenolate) ligands) have been prepared and characterized herein. These complexes form active olefin polymerization catalysts when combined with activators, such as non coordinating anion or alumoxane activators. Useful bis(aryl phenolate)pyridine complexes comprise a tridentate bis(aryl phenolate)pyridine ligand that is coordinated to a group 4 transition metal with the formation of two eight-membered rings.

[0051] This invention also relates to a metal complex comprising: a metal selected from groups 3-6 or Lanthanide metals, and a tridentate, dianionic ligand containing two anionic donor groups and a neutral Lewis base donor, wherein the neutral Lewis base donor is covalently bonded between the two anionic donors, and wherein the metal-ligand complex features a pair of 8-membered metallocycle rings.

[0052] This invention relates to catalyst systems comprising activator, optional support and one or more catalyst compounds as described herein.

[0053] This invention also relates to process to polymerize olefins using the catalyst compounds described herein comprising contacting one or more olefins with a catalyst system comprising an activator, optional support, and a catalyst compound described herein.

[0054] The present disclosure also relates to a catalyst system comprising a transition metal compound and an activator compound as described herein, to the use of such activator compounds for activating a transition metal compound in a catalyst system for polymerizing olefins, and to processes for polymerizing olefins, the process comprising contacting under polymerization conditions one or more olefins with a catalyst system comprising a transition metal compound and activator compounds, where aromatic solvents, such as toluene, are absent (e.g. present at zero mol% relative to the moles of activator, alternately present at less than 1 mol%, preferably the catalyst system, the polymerization reaction and/or the polymer produced are free of“detectable aromatic hydrocarbon solvent,” such as toluene). For purposes of the present disclosure,“detectable aromatic hydrocarbon solvent” means 0.1 mg/m ² or more as determined by gas phase chromatography. For purposes of the present disclosure,“detectable toluene” means 0.1 mg/m ² or more as determined by gas phase chromatography.

[0055] The polyalpha-olefins produced herein preferably contain 0 ppm (alternately less than 1 ppm) of aromatic hydrocarbon. Preferably, the polyalpha-olefins produced herein contain 0 ppm (alternately less than 1 ppm) of toluene.

[0056] The catalyst systems used herein preferably contain 0 ppm (alternately less than 1 ppm) of aromatic hydrocarbon. Preferably, the catalyst systems used herein contain 0 ppm (alternately less than 1 ppm) of toluene.

Catalyst Compounds

[0057] The terms“catalyst”,“compound”,“catalyst compound”, and“complex” may be used interchangeably to describe a transition metal or Lanthanide metal complex that forms an olefin polymerization catalyst when combined with a suitable activator.

[0058] The catalyst complexes of the present invention comprise a metal selected from groups 3, 4, 5 or 6 or Lanthanide metals of the Periodic Table of the Elements, a tridentate dianionic ligand containing two anionic donor groups and a neutral heterocyclic Lewis base donor, wherein the heterocyclic donor is covalently bonded between the two anionic donors. Preferably the dianionic, tridentate ligand features a central heterocyclic donor group and two phenolate donors and the tridentate ligand coordinates to the metal center to form two eight- membered rings.

[0059] The metal is preferably selected from group 3, 4, 5, or 6 elements. Preferably the metal, M, is a group 4 metal. Most preferably the metal, M, is zirconium or hafnium.

[0060] Preferably the heterocyclic Lewis base donor features a nitrogen or oxygen donor atom. Preferred heterocyclic groups include derivatives of pyridine, pyrazine, pyrimidine, triazine, thiazole, imidazole, thiophene, oxazole, thiazole, furan, and substituted variants of thereof. Preferably the heterocyclic Lewis base lacks hydrogen(s) in the position alpha to the donor atom. Particularly preferred heterocyclic Lewis base donors include pyridine, 3-substituted pyridines, and 4-substituted pyridines.

[0061] The anionic donors of the tridentate dianionic ligand may be arylthiolates, phenolates, or anilides. Preferred anionic donors are phenolates. It is preferred that the tridentate dianionic ligand coordinates to the metal center to form a complex that lacks a mirror plane of symmetry. It is preferred that the tridentate dianionic ligand coordinates to the metal center to form a complex that has a two-fold rotation axis of symmetry; when determining the symmetry of the bis(phenolate) complexes only the metal and dianionic tridentate ligand are considered (i.e. ignore remaining ligands).

[0062] The bis(phenolate) ligands useful in the present invention are preferably tridentate dianionic ligands that coordinate to the metal M in such a fashion that a pair of 8-membered metallocycle rings are formed. The bis(phenolate) ligands wrap around the metal to form a complex with a 2-fold rotation axis, thus giving the complexes C ₂ symmetry. The C ₂ geometry and the 8-membered metallocycle rings are features of these complexes that make them effective catalyst components for the production of polyolefins, particularly isotactic poly(alpha olefins). If the ligands were coordinated to the metal in such a manner that the complex had mirror-plane (C _s ) symmetry, then the catalyst would be expected to produce only atactic poly(alpha olefins); these symmetry-reactivity rules are summarized by Bercaw, J. E. (2009) in Macromolecules, v.42, pp. 8751-8762. The pair of 8-membered metallocycle rings of the inventive complexes is also a notable feature that is advantageous for catalyst activity, temperature stability, and isoselectivity of monomer enchainment. Related group 4 complexes featuring smaller 6-membered metallocycle rings are known {Macromolecules 2009, 42, 8751- 8762) to form mixtures of C ₂ and Cs symmetric complexes when used in olefin polymerizations and are thus not well suited to the production of highly isotactic poly (alpha olefins).

[0063] Bis(phenolate) ligands that contain oxygen donor groups (i.e. E = E’ = oxygen in Formula (I)) in the present invention are preferably substituted with alkyl, substituted alkyl, aryl, or other groups. It is advantageous that each phenolate group be substituted in the ring position that is adjacent to the oxygen donor atom. It is preferred that substitution at the position adjacent to the oxygen donor atom be an alkyl group containing 1-20 carbon atoms. It is preferred that substitution at the position next to the oxygen donor atom be a non-aromatic cyclic alkyl group with one or more five- or six-membered rings. It is preferred that substitution at the position next to the oxygen donor atom be a cyclic tertiary alkyl group. It is highly preferred that substitution at the position next to the oxygen donor atom be adamantan- 1-yl or substituted adamantan-l-yl.

[0064] The neutral heterocyclic Lewis base donor is covalently bonded between the two anionic donors via“linker groups” that join the heterocyclic Lewis base to the phenolate groups. The“linker groups” are indicated by (A ³ A ² ) and (A ² A ³ ) in Formula (I). The choice of each linker group may affect the catalyst performance, such as the tacticity of the poly(alpha olefin) produced. Each linker group is typically a C ₂ -C40 divalent group that is two-atoms in length. One or both linker groups may independently be phenylene, substituted phenylene, heteroaryl, vinylene, or a non-cyclic two-carbon long linker group. When one or both linker groups are phenylene, the alkyl substituents on the phenylene group may be chosen to optimize catalyst performance. Typically, one or both phenylenes may be unsubstituted or may be independently substituted with C ₁ to C ₂ 0 alkyl, such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, or an isomer thereof, such as isopropyl, etc.

[0112] Catalyst compounds that are particularly useful in this invention include those represented by one or more of the formulas:

Complex 19

Complex 20 [0113] In some embodiments, two or more different catalyst compounds are present in the catalyst system used herein. In some embodiments, two or more different catalyst compounds are present in the reaction zone where the process(es) described herein occur. It is preferable to use the same activator for the transition metal compounds, however, two different activators, such as a non-coordinating anion activator and an alumoxane, can be used in combination. If one or more transition metal compounds contain an X group which is not a hydride, hydrocarbyl, or substituted hydrocarbyl, then the alumoxane can be contacted with the transition metal compounds prior to addition of the non-coordinating anion activator.

[0114] The two transition metal compounds (pre-catalysts) may be used in any ratio. Preferred molar ratios of (A) transition metal compound to (B) transition metal compound fall within the range of (A: B) 1: 1000 to 1000: 1, alternatively 1 : 100 to 500: 1, alternatively l: 10 to 200: 1, alternatively 1: 1 to 100: 1, and alternatively 1: 1 to 75: 1, and alternatively 5: 1 to 50: 1. The particular ratio chosen will depend on the exact pre-catalysts chosen, the method of activation, and the end product desired. In a particular embodiment, when using the two pre catalysts, where both are activated with the same activator, useful mole percents, based upon the molecular weight of the pre-catalysts, are 10 to 99.9% A to 0.1 to 90%B, alternatively 25 to 99% A to 0.5 to 50% B, alternatively 50 to 99% A to 1 to 25% B, and alternatively 75 to 99% A to 1 to 10%B.

Methods to Prepare the Catalyst Compounds.

Ligand synthesis

[0115] The bis(phenol) ligands may be prepared using the general methods shown in Scheme 1. The formation of the bis(phenol) ligand by the coupling of compound A with compound B (method 1) may be accomplished by known Pd- and Ni-catalyzed couplings, such as Negishi, Suzuki, or Kumada couplings. The formation of the bis(phenol) ligand by the coupling of compound C with compound D (method 2) may also be accomplished by known Pd- and Ni-catalyzed couplings, such as Negishi, Suzuki, or Kumada couplings. Compound D may be prepared from compound E by reaction of compound E with either an organolithium reagent or magnesium metal, followed by optional reaction with a main-group metal halide (e.g. ZnCl ₂ ) or boron-based reagent (e.g. B(O ⁱ Pr)v ⁱ PrOB(pin)). Compound E may be prepared in a non-catalyzed reaction from by the reaction of an aryllithium or aryl Grignard reagent (compound F) with a dihalogenated arene (compound G), such as l-bromo-2-chlorobenzene. Compound E may also be prepared in a Pd- or Ni-catalyzed reaction by reaction of an arylzinc or aryl-boron reagent (compound F) with a dihalogenated arene (compound G).

where M’ is a group 1, 2, 12, or 13 element or substituted element such as Li, MgCl, MgBr, ZnCl, B(OH)2, B(pinacolate), P is a protective group such as methoxymethyl (MOM), tetrahydropyranyl (THP), t-butyl, allyl, ethoxymethyl, trialkylsilyl, t-butyldimethylsilyl, or benzyl, R is a C ₁ -C ₄₀ alkyl, substituted alkyl, aryl, tertiary alkyl, cyclic tertiary alkyl, adamantanyl, or substituted adamantanyl and each X' and X is halogen, such as Cl, Br, F or I.

[0116] It is preferred that the bis(phenol) ligand and intermediates used for the preparation of the bis(phenol) ligand are prepared and purified without the use of column chromatography. This may be accomplished by a variety of methods that include distillation, precipitation and washing, formation of insoluble salts (such as by reaction of a pyridine derivative with an organic acid), and liquid-liquid extraction. Preferred methods include those described in Practical Process Research and Development - A Guide for Organic Chemists by Neal C. Anderson (ISBN: 1493300125X).

Synthesis of carbene bis(phenol) ligands

[0117] The general synthetic method to produce carbene bis(phenol) ligands is shown in Scheme 2. A substituted phenol can be ortho-brominated then protected by a known phenol protecting group, such as MOM, THP, t-butyldimethylsilyl (TBDMS), benzyl (Bn), etc. The bromide is then converted to a boronic ester (compound I) or boronic acid which can be used in a Suzuki coupling with bromoaniline. The biphenylaniline (compound J) can be bridged by reaction with dibromoethane or condensation with oxalaldehyde, then deprotected (compound K). Reaction with triethyl orthoformate forms an iminium salt that is deprotonated to a carbene.

[0118] The substituted phenol (compound H) dissolved in methylene chloride, is added an equivalent of N-bromosuccinimide and 0.1 equivalent of diisopropylamine. After stirring at ambient temperature until completion, the reaction is quenched with a 10% solution of HC1. The organic portion is washed with brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to give a bromophenol, typically as a solid. The substituted bromophenol, methoxymethylchloride, and potassium carbonate are dissolved in dry acetone and stirred at ambient temperature until completion of the reaction. The solution is filtered and the filtrate concentrated to give protected phenol (compound I). Alternatively, the substituted bromophenol and an equivalent of dihydropyran is dissolved in methylene chloride and cooled to 0°C. A catalytic amount of para-toluenesulfonic acid is added and the reaction stirred for 10 minutes, then quenched with trimethylamine. The mixture is washed with water and brine, then dried over magnesium sulfate, filtered, and concentrated under reduced pressure to give a tetrahydropyran-protected phenol.

[0119] Aryl bromide (compound I) is dissolved in THF and cooled to -78°C. n-Butyllithium is added slowly, followed by trimethoxy borate. The reaction is allowed to stir at ambient temperature until completion. The solvent is removed and the solid boronic ester washed with pentane. A boronic acid can be made from the boronic ester by treatment with HC1. The boronic ester or acid is dissolved in toluene with an equivalent of ortho-bromoaniline and a catalytic amount of palladium tetrakistriphenylphosphine. An aqueous solution of sodium carbonated is added and the reaction heated at reflux overnight. Upon cooling, the layers are separated and the aqueous layer extracted with ethyl acetate. The combined organic portions are washed with brine, dried (MgS04), filtered, and concentrated under reduced pressure. Column chromatography is typically used to purify the coupled product (compound J).

[0120] The aniline (compound J) and dibromoethane (0.5 equiv.) are dissolved in acetonitrile and heated at 60°C overnight. The reaction is filtered and concentrated to give an ethylene bridged dianiline. The protected phenol is deprotected by reaction with HC1 to give a bridged bisamino(biphenyl)ol (compound K).

[0121] The diamine (compound K) is dissolved in triethylorthoformate. Ammonium chloride is added and the reaction heated at reflux overnight. A precipitate is formed which is collected by filtration and washed with ether to give the iminium salt. The iminium chloride is suspended in THF and treated with lithium or sodium hexamethyldisilylamide. Upon completion, the reaction is filtered and the filtrate concentrated to give the carbene ligand. Preparation of bis(phenolate) complexes

[0122] Transition metal or Lanthanide metal bis(phenolate) complexes are used as catalyst components for olefin polymerization in the present invention. The terms“catalyst” and “catalyst complex” are used interchangeably. The preparation of transition metal or Lanthanide metal bis(phenolate) complexes may be accomplished by reaction of the bis(phenol) ligand with a metal reactant containing anionic basic leaving groups. Typical anionic basic leaving groups include dialky lamido, benzyl, phenyl, hydrido, and methyl. In this reaction, the role of the basic leaving group is to deprotonate the bis(phenol) ligand. Suitable metal reactants for this type of reaction include, but are not limited to, HfBn ₄ (Bn = CH ₂ Ph), ZrBn ₄ , TiBn ₄ , ZrBn ₂ Cl ₂ (OEt ₂ ). HfBn ₂ Cl ₂ (OEt ₂ ) ₂ , Zr(NMe ₂ ) ₂ Cl ₂ (dimethoxyethane),

Hf(NMe2)2Cl2(dimethoxyethane), Hf(NMe ₂ ) ₄ , Zr(NMe ₂ ) ₄ , and Hf(NEt ₂ ) ₄ . Suitable metal reagents also include ZrMe4, HfMe4, and other group 4 alkyls that may be formed in situ and used without isolation.

[0123] A second method for the preparation of transition metal or Lanthanide bis(phenolate) complexes is by reaction of the bis(phenol) ligand with an alkali metal or alkaline earth metal base (e.g., Na, BuLi, 'PrMgBr) to generate deprotonated ligand, followed by reaction with a metal halide (e.g., HfCl ZrCL ₄ ) to form a bis(phenolate) complex. Bis(phenoate) metal complexes that contain metal-halide, alkoxide, or amido leaving groups may be alkylated by reaction with organolithium, Grignard, and organoaluminum reagents. In the alkylation reaction the alkyl groups are transferred to the bis(phenolate) metal center and the leaving groups are removed. Reagents typically used for the alkylation reaction include, but are not limited to, MeLi, MeMgBr, AlMe ₃ , Al( ⁱ Bu) ₃ . AlOct _3, and PhCH ₂ MgCl. Typically 2 to 20 molar equivalents of the alkylating reagent are added to the bis(phenolate) complex. The alkylations are generally performed in etherial or hydrocarbon solvents or solvent mixtures at temperatures typically ranging from -80°C to 120°C.

Activators

[0124] The terms“cocatalyst” and“activator” are used herein interchangeably.

[0125] The catalyst systems described herein typically comprises a catalyst complex, such as the transition metal or Lanthanide bis(phenolate) complexes described above, and an activator such as alumoxane (the term alumoxane is synonymous with aluminoxane) or a non coordinating anion. These catalyst systems may be formed by combining the catalyst components described herein with activators in any manner known from the literature including combining them with supports, such as silica. The catalyst systems may also be added to or generated in solution polymerization or bulk polymerization (in the monomer). Catalyst systems of the present disclosure may have one or more activators and one, two or more catalyst components. Activators are defined to be any compound which can activate any one of the catalyst compounds described above by converting the neutral metal compound to a catalytically active metal compound cation. Non-limiting activators, for example, include alumoxanes, ionizing activators, which may be neutral or ionic, and conventional-type cocatalysts. Preferred activators typically include alumoxane compounds, modified alumoxane compounds, and ionizing anion precursor compounds that abstract a reactive metal ligand making the metal compound cationic and providing a charge-balancing non-coordinating or weakly coordinating anion, e.g. a non-coordinating anion.

Alumoxane Activators

[0126] Alumoxane activators are utilized as activators in the catalyst systems described herein. Alumoxanes are generally oligomeric compounds containing -A^R^-O- sub-units, where R ¹ is an alkyl group. Examples of alumoxanes include methylalumoxane (MAO), modified methylalumoxane (MMAO), ethylalumoxane and isobutylalumoxane. Alkylalumoxanes and modified alkylalumoxanes are suitable as catalyst activators, particularly when the abstractable ligand is an alkyl, halide, alkoxide or amide. Mixtures of different alumoxanes and modified alumoxanes may also be used. It may be preferable to use a visually clear methylalumoxane. A cloudy or gelled alumoxane can be filtered to produce a clear solution or clear alumoxane can be decanted from the cloudy solution. A useful alumoxane is a modified methyl alumoxane (MMAO) cocatalyst type 3A (commercially available from Akzo Chemicals, Inc. under the trade name Modified Methylalumoxane type 3A, covered under patent number U.S. Patent No. 5,041,584). Another useful alumoxane is solid polymethylaluminoxane as described in US 9,340,630; US 8,404,880; and US 8,975,209.

[0127] When the activator is an alumoxane (modified or unmodified), typically the maximum amount of activator is at up to a 5,000-fold molar excess Al/M over the catalyst compound (per metal catalytic site). The minimum activator-to-catalyst-compound is a 1: 1 molar ratio. Alternate preferred ranges include from 1 : 1 to 500: 1, alternately from 1 : 1 to 200: 1, alternately from 1: 1 to 100: 1, or alternately from 1 : 1 to 50: 1.

[0128] In an alternate embodiment, little or no alumoxane is used in the polymerization processes described herein. Preferably, alumoxane is present at zero mole %, alternately the alumoxane is present at a molar ratio of aluminum to catalyst compound transition metal less than 500: 1, preferably less than 300: 1, preferably less than 100: 1, preferably less than 1: 1. Ionizing/Non Coordinating Anion Activators

[0129] The term "non-coordinating anion" (NCA) means an anion which either does not coordinate to a cation or which is only weakly coordinated to a cation thereby remaining sufficiently labile to be displaced by a neutral Lewis base. Further, the anion will not transfer an anionic substituent or fragment to the cation so as to cause it to form a neutral transition metal compound and a neutral by-product from the anion. Non-coordinating anions useful in accordance with this invention are those that are compatible, stabilize the transition metal cation in the sense of balancing its ionic charge at +1, and yet retain sufficient lability to permit displacement during polymerization. The termNCA is also defined to include multicomponent NCA-containing activators, such as N,N-dimethylaniliniumtetrakis(pentafluorophenyl)borate, that contain an acidic cationic group and the non-coordinating anion. The term NCA is also defined to include neutral Lewis acids, such as tris(pentafluorophenyl)boron, that can react with a catalyst to form an activated species by abstraction of an anionic group. Any metal or metalloid that can form a compatible, weakly coordinating complex may be used or contained in the non-coordinating anion. Suitable metals include, but are not limited to, aluminum, gold, and platinum. Suitable metalloids include, but are not limited to, boron, aluminum, phosphorus, and silicon.

[0130] It is within the scope of this invention to use an ionizing activator, neutral or ionic. It is also within the scope of this invention to use neutral or ionic activators alone or in combination with alumoxane or modified alumoxane activators.

[0161] In one embodiment, the borate activator comprises tetrakis(pentafluorophenyl)borate.

[0162] Anions for use in the non-coordinating anion activators described herein also include those represented by Formula 7, below:

Formula 7

wherein:

M* is a group 13 atom, preferably B or Al, preferably B;

each R ¹¹ is, independently, a halide, preferably a fluoride;

each R ¹² is, independently, a halide, a Ce to C ₂₀ substituted aromatic hydrocarbyl group or a siloxy group of the formula -O-Si-R ^a , where R ^a is a C ₁ to C ₂₀ hydrocarbyl or hydrocarbylsilyl group, preferably R ¹² is a fluoride or a perfluorinated phenyl group;

each R ¹³ is a halide, a Ce to C ₂₀ substituted aromatic hydrocarbyl group or a siloxy group of the formula -O-Si-Ra, where R ^a is a C ₁ to C ₂₀ hydrocarbyl or hydrocarbylsilyl group, preferably R ¹³ is a fluoride or a C ₆ perfluorinated aromatic hydrocarbyl group;

wherein R ¹² and R ¹³ can form one or more saturated or unsaturated, substituted or unsubstituted rings, preferably R ¹² and R ¹³ form a perfluorinated phenyl ring. Preferably the anion has a molecular weight of greater than 700 g/mol, and, preferably, at least three of the substituents on the M* atom each have a molecular volume of greater than 180 cubic A. [0163] "Molecular volume" is used herein as an approximation of spatial steric bulk of an activator molecule in solution. Comparison of substituents with differing molecular volumes allows the substituent with the smaller molecular volume to be considered "less bulky" in comparison to the substituent with the larger molecular volume. Conversely, a substituent with a larger molecular volume may be considered "more bulky" than a substituent with a smaller molecular volume.

[0164] Molecular volume may be calculated as reported in "A Simple "Back of the Envelope" Method for Estimating the Densities and Molecular Volumes of Liquids and Solids," Journal of Chemical Education, v.71(ll), November 1994, pp. 962-964. Molecular volume (MV), in units of cubic Å, is calculated using the formula: MV = 8.3V _S , where V _s is the scaled volume. V _s is the sum of the relative volumes of the constituent atoms, and is calculated from the molecular formula of the substituent using Table A below of relative volumes. For fused rings, the V _s is decreased by 7.5% per fused ring. The Calculated Total MV of the anion is the sum of the MV per substituent, for example, the MV of perfluorophenyl is 183 Å ³ , and the Calculated Total MV for tetrakis(perfluorophenyl)borate is four times 183 Å ³ , or 732 Å ³ .

Table A

[0165] Exemplary anions useful herein and their respective scaled volumes and molecular volumes are shown in Table B below. The dashed bonds indicate bonding to boron.

Table B

[0166] The activators may be added to a polymerization in the form of an ion pair using, for example, [M2HTH]+ [NCA]- in which the di(hydrogenated tallow)methylamine (“M2HTH”) cation reacts with a basic leaving group on the transition metal complex to form a transition metal complex cation and [NCA]-. Alternatively, the transition metal complex may be reacted with a neutral NCA precursor, such as B(C ₆ F ₅ ) ₃ , which abstracts an anionic group from the complex to form an activated species. Useful activators include di(hydrogenated tallow)methylammonium[tetrakis(pentafluorophenyl)borate] (i.e., [M2HTH]B(C ₆ F ₅ ) ₄ ) and di(octadecyl)tolylammonium [tetrakis(pentafluorophenyl)borate] (i.e., [DOdTH]B(C ₆ F ₅ ) ₄ ).

A particularly useful range is from 0.5: 1 to 10: 1, preferably 1: 1 to 5: 1.

[0175] It is also within the scope of the present disclosure that the catalyst compounds can be combined with combinations of alumoxanes and NCA's (see for example, US 5,153,157; US 5,453,410; EP 0 573 120 Bl; WO 1994/007928; and WO 1995/014044 (the disclosures of which are incorporated herein by reference in their entirety) which discuss the use of an alumoxane in combination with an ionizing activator). Optional Scavengers, Co- Activators, Chain Transfer Agents

[0176] In addition to activator compounds, scavengers or co-activators may be used. A scavenger is a compound that is typically added to facilitate polymerization by scavenging impurities. Some scavengers may also act as activators and may be referred to as co-activators. A co-activator, that is not a scavenger, may also be used in conjunction with an activator in order to form an active catalyst. In some embodiments a co-activator can be pre-mixed with the transition metal compound to form an alkylated transition metal compound.

[0177] Co-activators can include alumoxanes such as methylalumoxane, modified alumoxanes such as modified methylalumoxane, and aluminum alkyls such trimethylaluminum, tri-isobutylaluminum, triethylaluminum, and tri-isopropylaluminum, tri- n-hexylaluminum, tri-n-octylaluminum, tri-n-decylaluminum or tri-n-dodecylaluminum. Co-activators are typically used in combination with Lewis acid activators and ionic activators when the pre-catalyst is not a dihydrocarbyl or dihydride complex. Sometimes co-activators are also used as scavengers to deactivate impurities in feed or reactors.

[0178] Aluminum alkyl or organoaluminum compounds which may be utilized as scavengers or co-activators include, for example, trimethylaluminum, triethylaluminum, triisobutylaluminum, tri-n-hexylaluminum, tri-n-octylaluminum, and dialkyl zinc, such as diethyl zinc.

[0179] Chain transfer agents may be used in the compositions and or processes described herein. Useful chain transfer agents are typically hydrogen, alkylalumoxanes, a compound represented by the formula AIR3, ZnR.2 (where each R is, independently, a C ₁ -Cx aliphatic radical, preferably methyl, ethyl, propyl, butyl, penyl, hexyl octyl or an isomer thereol) or a combination thereof, such as diethyl zinc, trimethylaluminum, triisobutylaluminum, trioctylaluminum, or a combination thereof.

[0180] The catalyst system comprises an inert support material. Preferably the supported material is a porous support material, for example, talc, and inorganic oxides. Other support materials include zeolites, clays, organoclays, or any other organic or inorganic support material and the like, or mixtures thereof.

[0181] Preferably, the support material is an inorganic oxide in a finely divided form. Suitable inorganic oxide materials for use in catalyst systems herein include Groups 2, 4, 13, and 14 metal oxides, such as silica, alumina, and mixtures thereof. Other inorganic oxides that may be employed either alone or in combination with the silica, or alumina are magnesia, titania, zirconia, and the like. Other suitable support materials, however, can be employed, for example, finely divided functionalized polyolefins, such as finely divided polyethylene. Particularly useful supports include magnesia, titania, zirconia, montmorillonite, phyllosilicate, zeolites, talc, clays, and the like. Also, combinations of these support materials may be used, for example, silica-chromium, silica-alumina, silica-titania, and the like. Preferred support materials include A1 ₂ O ₃ , ZrO ₂ , SiO ₂ , and combinations thereof, more preferably SiO ₂ , A1 ₂ O ₃ , or SiO ₂ /Al ₂ O ₃ . The support may also comprises a solid oxide optionally treated with an electron-withdrawing anion, wherein the solid oxide is selected from the group consisting of silica, alumina, silica-alumina, silica-zirconia, alumina-zirconia, aluminum phosphate, heteropolytungstates, titania, magnesia, boria, zinc oxide, mixed oxides thereof, and mixture(s) thereof; and the electron-withdrawing anion is selected from the group consisting of fluoride, chloride, bromide, phosphate, triflate, bisulfate, sulfate, and combination(s) thereof.

[0182] It is preferred that the support material, most preferably an inorganic oxide, has a surface area in the range of from about 10 to about 700 m ² /g, pore volume in the range of from about 0.1 to about 4.0 cc/g and average particle size in the range of from about 5 to about 500 pm. More preferably, the surface area of the support material is in the range of from about 50 to about 500 m ² /g, pore volume of from about 0.5 to about 3.5 cc/g and average particle size of from about 10 to about 200 pm. Most preferably the surface area of the support material is in the range is from about 100 to about 400 m ² /g, pore volume from about 0.8 to about 3.0 cc/g and average particle size is from about 5 to about 100 pm. The average pore size of the support material useful in the invention is in the range of from 10 to 1000 A, preferably 50 to about 500 A, and most preferably 75 to about 350 A. In some embodiments, the support material is a high surface area, amorphous silica (surface area=300 m ² /gm; pore volume of 1.65 cm ³ /gm). Preferred silicas are available under the tradenames of DAVISON™ 952 or DAVISON™ 955 by the Davison Chemical Division of W.R. Grace and Company. In other embodiments DAVISON™ 948 is used. Other preferred silicas may be obtained from PQ Corporation, for example ES757, ES70, and ES70X.

[0183] The support material should be dry, that is, free of absorbed water. Drying of the support material can be effected by heating or calcining at about 100°C to about 1,000°C, preferably at least about 600°C. When the support material is silica, it is heated to at least 200°C, preferably about 200°C to about 850°C, and most preferably at about 600°C; and for a time of about 1 minute to about 100 hours, from about 12 hours to about 72 hours, or from about 24 hours to about 60 hours. The calcined support material may have at least some reactive hydroxyl (OH) groups to produce supported catalyst systems of this invention. The calcined support material is then contacted with at least one polymerization catalyst comprising at least one catalyst compound and an activator.

[0184] The support material is slurried in a non-polar solvent and the resulting slurry is contacted with a solution of a catalyst compound and an activator. In some embodiments, the slurry of the support material is first contacted with the activator for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. The solution of the catalyst compound is then contacted with the isolated support/activator. In some embodiments, the supported catalyst system is generated in situ. In alternate embodiment, the slurry of the support material is first contacted with the catalyst compound for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. The slurry of the supported catalyst compound is then contacted with the activator solution.

Contact times typically range from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours.

[0186] Suitable non-polar solvents are materials in which all of the reactants used herein, i.e., the activator, and the catalyst compound, are at least partially soluble and which are liquid at reaction temperatures. Preferred non-polar solvents are alkanes, such as isopentane, hexane, n-heptane, octane, nonane, and decane, although a variety of other materials including cycloalkanes, such as methylcyclohexane, aromatics, such as benzene, toluene, and ethylbenzene, may also be employed.

Polymerization Processes

[0187] For the polymerization processes described herein, the term "continuous" means a system that operates without interruption or cessation. For example a continuous process to produce a polymer would be one where the reactants are continually introduced into one or more reactors and polymer product is continually withdrawn.

[0188] A solution polymerization means a polymerization process in which the polymer is dissolved in a liquid polymerization medium, such as an inert solvent or monomer(s) or their blends. A solution polymerization is typically homogeneous. A homogeneous polymerization is one where the polymer product is dissolved in the polymerization medium. Such systems are preferably not turbid as described in J. Vladimir Oliveira, et al. (2000) Ind. Eng. Chem. Res., v.29, pg. 4627.

[0189] A bulk polymerization means a polymerization process in which the monomers and/or comonomers being polymerized are used as a solvent or diluent using little or no inert solvent as a solvent or diluent. A small fraction of inert solvent might be used as a carrier for catalyst and scavenger. A bulk polymerization system contains less than 25 wt% of inert solvent or diluent, preferably less than 10 wt%, preferably less than 1 wt%, preferably 0 wt%.

[0190] In embodiments herein, the invention relates to polymerization processes where monomer (such as propylene), and optionally comonomer, are contacted with a catalyst system comprising an activator, a support and at least one catalyst compound, as described above. The catalyst compound, support, and activator may be combined in any order, and are combined typically prior to contacting with the monomer.

[0191] Monomers useful herein include substituted or unsubstituted C2 to C40 alpha olefins, preferably C ₂ to C ₂₀ alpha olefins, preferably C ₂ to C ₁₂ alpha olefins, preferably ethylene, propylene, butene, pentene, hexene, heptene, octene, nonene, decene, undecene, dodecene and isomers thereof. In a preferred embodiment of the invention, the monomer comprises propylene and an optional comonomers comprising one or more ethylene or C ₄ to C ₄₀ olefins, preferably C ₄ to C ₂₀ olefins, or preferably C ₆ to C ₁₂ olefins. The C ₄ to C ₄₀ olefin monomers may be linear, branched, or cyclic. The C ₄ to C ₄₀ cyclic olefins may be strained or unstrained, monocyclic or polycyclic, and may optionally include heteroatoms and/or one or more functional groups. In another preferred embodiment, the monomer comprises ethylene and an optional comonomers comprising one or more C ₃ to C ₄₀ olefins, preferably C ₄ to C ₂₀ olefins, or preferably C ₆ to C ₁₂ olefins. The C ₃ to C ₄₀ olefin monomers may be linear, branched, or cyclic. The C ₃ to C ₄₀ cyclic olefins may be strained or unstrained, monocyclic or polycyclic, and may optionally include heteroatoms and/or one or more functional groups.

[0192] Exemplary C ₂ to C ₄₀ olefin monomers and optional comonomers include ethylene, propylene, butene, pentene, hexene, heptene, octene, nonene, decene, undecene, dodecene, norbomene, cyclopentene, cycloheptene, cyclooctene, cyclododecene, substituted derivatives thereof, and isomers thereof, preferably hexene, heptene, octene, nonene, decene, dodecene, cyclooctene, 5-methylcyclopentene, cyclopentene, norbomene, 5-ethylidene-2-norbomene, and their respective homologs and derivatives.

[0193] In a preferred embodiment one or more dienes are present in the polymer produced herein at up to 10 weight %, preferably at 0.00001 to 1.0 weight %, preferably 0.002 to 0.5 weight %, even more preferably 0.003 to 0.2 weight %, based upon the total weight of the composition. In some embodiments 500 ppm or less of diene is added to the polymerization, preferably 400 ppm or less, preferably or 300 ppm or less. In other embodiments at least [0194] Preferred diolefm monomers useful in this invention include any hydrocarbon structure, preferably C ₅ to C ₃₀ , having at least two unsaturated bonds, wherein at least two of the unsaturated bonds are readily incorporated into a polymer by either a stereospecific or a non-stereospecific catalyst(s). It is further preferred that the diolefm monomers be selected from non-conjugated diene monomers. More preferably, the diolefm monomers are linear di vinyl monomers, most preferably those containing from 5 to 30 carbon atoms. Examples of preferred dienes includepentadiene, hexadiene, heptadiene, octadiene, nonadiene, decadiene, undecadiene, dodecadiene, tridecadiene, tetradecadiene, pentadecadiene, hexadecadiene, heptadecadiene, octadecadiene, nonadecadiene, icosadiene, heneicosadiene, docosadiene, tricosadiene, tetracosadiene, pentacosadiene, hexacosadiene, heptacosadiene, octacosadiene, nonacosadiene, triacontadiene, particularly preferred dienes include 1,6-heptadiene, 1,7-octadiene, 1,8-nonadiene, 1,9-decadiene, 1,10-undecadiene, 1,11 -dodecadiene, 1,12- tridecadiene, 1,13 -tetradecadiene, divinylbenzene, and low molecular weight poly butadienes (Mw less than 1000 g/mol). Preferred cyclic dienes include cyclopentadiene, vinylnorbomene, norbomadiene, and dicyclopentadiene.

[0195] Polymerization processes of this invention can be carried out in any manner known in the art. Any suspension, bulk, slurry, or gas phase polymerization process known in the art can be used. Particularly, any suspension, slurry, high pressure tubular or autoclave process, or gas phase polymerization process known in the art can be used under polymerizable conditions. Such processes can be run in a batch, semi-batch, or continuous mode. Gas phase polymerization processes and slurry processes are preferred. Preferably the process is not a homogeneous polymerization process, e.g., a process where preferably at least 90 wt% of the product is soluble in the reaction media. In some embodiments, no solvent or diluent is present or added in the reaction medium, (except for the small amounts used as the carrier for the catalyst system or other additives, or amounts typically found with the monomer; e.g., propane in propylene). In a preferred embodiment of the invention, the process is a slurry process. As used herein the term“slurry polymerization process” means a polymerization process where a supported catalyst is employed and monomers are polymerized on the supported catalyst particles. At least 95 wt% of polymer products derived from the supported catalyst are in granular form as solid particles (not dissolved in the diluent).

[0196] In another embodiment of the invention, the polymerization is performed in the slurry phase. A slurry polymerization process generally operates between 1 to about 50 atmosphere pressure range (15 psi to 735 psi, 103 kPa to 5068 kPa) or even greater and temperatures as described above. In a slurry polymerization, a suspension of solid, particulate polymer is formed in a liquid polymerization diluent medium to which monomer and comonomers, along with catalysts, are added. The suspension including diluent is intermittently or continuously removed from the reactor where the volatile components are separated from the polymer and recycled, optionally after a distillation, to the reactor. The liquid diluent employed in the polymerization medium is typically an alkane having from 3 to 7 carbon atoms, preferably a branched alkane. The medium employed should be liquid under the conditions of polymerization and relatively inert. When a propane medium is used, the process is typically operated above the reaction diluent critical temperature and pressure. Often, a hexane or an isobutane medium is employed.

[0197] In an embodiment, a preferred polymerization technique useful in the invention is referred to as a particle form polymerization, or a slurry process where the temperature is kept below the temperature at which the polymer goes into solution. Such technique is known in the art, and described in for instance U.S. Patent No. 3,248,179. A preferred temperature in the particle form process is within the range of about 85°C to about 110°C. Two preferred polymerization methods for the slurry process are those employing a loop reactor and those utilizing a plurality of stirred reactors in series, parallel, or combinations thereof. Non-limiting examples of slurry processes include continuous loop or stirred tank processes. Also, other examples of slurry processes are described in U.S. Patent No. 4,613,484, which is herein fully incorporated by reference.

[0198] In a class of embodiments, the polymerization is performed in the gas phase, preferably, in a fluidized bed gas phase process. Generally, in a fluidized bed gas phase process used for producing polymers, a gaseous stream containing one or more monomers is continuously cycled through a fluidized bed in the presence of a catalyst under reactive conditions.

The polymers can be mixed together prior to being put into the extruder or may be mixed in an extruder.

[0216] The blends may be formed using conventional equipment and methods, such as by dry blending the individual components and subsequently melt mixing in a mixer, or by mixing the components together directly in a mixer, such as, for example, a Banbury mixer, a Haake mixer, a Brabender internal mixer, or a single or twin-screw extruder, which may include a compounding extruder and a side-arm extruder used directly downstream of a polymerization process, which may include blending powders or pellets of the resins at the hopper of the film extruder. Additionally, additives may be included in the blend, in one or more components of the blend, and/or in a product formed from the blend, such as a film, as desired. Such additives are well known in the art, and can include, for example: fillers; antioxidants (e.g., hindered phenolics such as IRGANOX™ 1010 or IRGANOX™ 1076 available from Ciba-Geigy); phosphites (e.g., IRGAFOS™ 168 available from Ciba-Geigy); anti-cling additives; tackifiers, such as polybutenes, terpene resins, aliphatic and aromatic hydrocarbon resins, alkali metal and glycerol stearates, and hydrogenated rosins; UV stabilizers; heat stabilizers; anti-blocking agents; release agents; anti-static agents; pigments; colorants; dyes; waxes; silica; fillers; talc; and the like.

[0217] Any of the foregoing polymers and compositions in combination with optional additives (see, for example, U.S. Patent Application Publication No. 2016/0060430, paragraphs [0082]-[0093]) may be used in a variety of end-use applications. Such end uses may be produced by methods known in the art. End uses include polymer products and products having specific end-uses. Exemplary end uses are films, film-based products, diaper backsheets, housewrap, wire and cable coating compositions, articles formed by molding techniques, e.g., injection or blow molding, extrusion coating, foaming, casting, and combinations thereof. End uses also include products made from films, e.g., bags, packaging, and personal care films, pouches, medical products, such as for example, medical films and intravenous (IV) bags. Films

[0218] Specifically, any of the foregoing polymers, such as the foregoing polypropylenes or blends thereof, may be used in a variety of end-use applications. Such applications include, for example, mono- or multi-layer blown, extruded, and/or shrink films. These films may be formed by any number of well-known extrusion or coextrusion techniques, such as a blown bubble film processing technique, wherein the composition can be extruded in a molten state through an annular die and then expanded to form a uni-axial or biaxial orientation melt prior to being cooled to form a tubular, blown film, which can then be axially slit and unfolded to form a flat film. Films may be subsequently unoriented, uniaxially oriented, or biaxially oriented to the same or different extents. One or more of the layers of the film may be oriented in the transverse and/or longitudinal directions to the same or different extents. The uniaxially orientation can be accomplished using typical cold drawing or hot drawing methods. Biaxial orientation can be accomplished using tenter frame equipment or a double bubble processes and may occur before or after the individual layers are brought together. For example, a polyethylene layer can be extrusion coated or laminated onto an oriented polypropylene layer or the polyethylene and polypropylene can be coextruded together into a film then oriented. Likewise, oriented polypropylene could be laminated to oriented polyethylene or oriented polyethylene could be coated onto polypropylene then optionally the combination could be oriented even further. Typically the films are oriented in the Machine Direction (MD) at a ratio of up to 15, preferably between 5 and 7, and in the Transverse Direction (TD) at a ratio of up to 15, preferably 7 to 9. However, in another embodiment the film is oriented to the same extent in both the MD and TD directions.

[0219] The films may vary in thickness depending on the intended application; however, films of a thickness from 1 to 50 pm are usually suitable. Films intended for packaging are usually from 10 to 50 pm thick. The thickness of the sealing layer is typically 0.2 to 50 pm. There may be a sealing layer on both the inner and outer surfaces of the film or the sealing layer may be present on only the inner or the outer surface.

[0220] In another embodiment, one or more layers may be modified by corona treatment, electron beam irradiation, gamma irradiation, flame treatment, or microwave. In a preferred embodiment, one or both of the surface layers is modified by corona treatment.

EXPERIMENTAL SMAO-1 Preparation

[0222] Methylalumoxane (MAO, 30 wt% in toluene, 891 grams) and 1,800 grams of toluene were added together in a 4L stirred reactor. This solution was stirred at 60 RPM for 5 minutes. ES70™ silica (741 grams, PQ Corporation, Malvern, Pennsylvania, calcined to 875°C under a flow of N2) was added. The slurry was heated at 100°C and stirred at 120 RPM for 3 hours. The temperature was reduced to 25°C and cooled to temperature over 2 hours. Once cooled, the vessel was stirred at 8 RPM and placed under vacuum for 60 hours. After emptying the vessel and sieving the supported MAO, supported MAO (SMAO) was collected.

Preparation of Scavenger A

[0223] ES70 silica (PQ Corp.) was dried for 3 hours at 100°C in a tube furnace under a slight flow of dry N2. To a 4 L conical reaction vessel was added 2.5 L of dry, deoxygenated n-hexane and 272 grams of triisobutylaluminum (Albemarle). The stirring rate was set to 120 rpm and 742 g of the silica was added. The slurry was stirred for 3 hours and then dried under vacuum at 25°C over the course of 16 hours. The dry solid was washed with 2 liters of dry, deoxygenated pentane (Sigma Aldrich) and then returned to the reaction vessel and dried under vacuum for 2 hours at 25°C.

Supported catalyst preparation for examples 1 and 2

[0224] 1.0 g of the SMAO-1 was added to a 20 mL vial and 5.0 mL of toluene was added.

The vial was placed on a shaker and a solution of the catalyst complex in toluene (40 mmol in 3.0 mL) was added dropwise. After shaking for 15 minutes the solid was isolated by filtration, washed with pentane (ca. 5 ml) and dried under vacuum.

Both 10% hydrogen in nitrogen (0.5 mg/g) and 1-hexene (0.1 g/g) were fed in ratio to the ethylene flow. The polymerization was halted after 60 minutes by venting the reactor. The polymer was washed twice with water to remove salt and then dried in air for at least two days. Details are presented in Table A below. The data are reported in Table A.

[0235] High Throughput Polymerization Conditions: Unless stated otherwise, propylene homopolymerizations and ethylene-propylene copolymerizations were carried out in a parallel, pressure reactor, as generally described in U.S. Pat. Nos. 6,306,658; 6,455,316; 6,489,168; WO 00/09255; and Murphy et al. (2003) J. Am. Chem. Soc., v.125, pp.4306-4317, each of which is fully incorporated herein by reference for US purposes. Although the specific quantities, temperatures, solvents, reactants, reactant ratios, pressures, and other variables may have changed from one polymerization run to the next, the following describes a typical polymerization performed in a parallel, pressure reactor.

Preparation of support materials

[0236] SMAO-2– Silica supported MAO for propylene polymerization: In a celstir bottle, 20.0 g of silica (DM L403, AGC Chemicals, 200°C calcination) and 91.2 g of toluene were mixed. The silica slurry was then allowed to cool in the freezer for 30 minutes. In a square bottle, 31.8 g MAO (30% toluene solution, GRACE chemicals), based on 7.5 mmol Al/g silica) was charged in and also cooled down in the freezer for 30 minutes. After 30 minutes, the cold MAO solution was added slowly into the silica slurry bottle by pipette. The solution was allowed to stir at room temperature for 1 hour. After 1 hour, the oil bath was heated up to 100°C and the solution stirred at 100°C for 3 hours. After 2.5 hours of stirring, the celstir bottle was taken off the heat and continued to stir for another 30 minutes. The mixture was then filtered, washed 2 x 20 g toluene (to remove toluene soluble MAO) and 2 x 20 g isohexane (to remove toluene for easier drying). The product was dried under vacuum overnight.

SMAOF - Fluorided Alumina Silica.

[0237] A mixture of 6 wt% (NH4)2SiF6 and 94 wt % of 5% Al on ES70™ silica (PQ Corporation, Malvern, Pennsylvania) was fluidized with a stream of dry air and heated at 30– 50°C/h up to 650°C, held for 3 hours, then cooled to ambient temperature then the air was removed with a N ₂ purge. The resulting material was treated with MAO (based on 7.5 mmol Al/g silica) in a similar fashion as with SMAO-2. The material was then filtered, washed with toluene and pentane and dried in vacuo.

MMT– Acid treated montmorillonite

[0238] 56.6 mL water and 16.65 g of H ₂ SO ₄ mixed into celstir bottle and placed into 90°C heated oil bath. To this mixture was added clay mineral (10 g, K-10 MMT™, Aldrich). The mixture was allowed to stir for 8 hours at 90°C. Upon cooling to room temperature, the mixture was filtered and washed with 4 x 100 mL of deionized water. The material was then dried in oven at 200°C under vacuum for 2 hours.

General procedure for preparation of supported catalysts

[0239] 1 g of support material (SMAO-2, SMAOF or MMT) was suspended in 5 mL of toluene and placed on a shaker. Optionally, TIBAL (7 wt% relative to support) was added, and the resulting mixture was allowed to shake for 15 minutes. After 15 minutes, either catalyst 5 or 6 were added as toluene solutions (based on either 40 or 20 µmol/g) to the support material mixture. The mixture was allowed to react for 3 hours. After 3 hours, the mixture was filtered and the solid was washed with toluene (5 mL) and pentane (2 x 5 mL) and dried in vacuo to give a supported catalysts as white or off-white solids. Optionally, the supported catalysts were slurried in mineral oil (degassed at 100°C for 2 hours).

[0240] Propylene Polymerization (High-Throughput Conditions): A pre-weighed glass vial insert and disposable stirring paddle were fitted to each reaction vessel of the reactor, which contains 48 individual reaction vessels. The reactor was then closed and propylene (typically 4 mL for homopolymers and 2 mL for copolymers with ethylene) was introduced to each vessel as a condensed gas liquid (typically 4 or 2 mL) (as shown in examples in Tables B and C). Then solvent (typically isohexane) and scavenger (typically triisobutyl aluminum, TIBAL) was added to bring the total reaction volume, including the subsequent additions, to 5 mL and the reactor vessels were heated to their set temperature (usually from about 50°C to about 110°C). The reactors were then additionally pressurized with ethylene (between 20-150 psig, applicable to EP copolymers). The contents of the vessel were stirred at 800 rpm. A supported catalyst slurry (typically corresponding to 0.45 mg of solid catalyst) was then injected into the reaction vessel along with 500 microliters of toluene. Equivalence is determined based on the mol equivalents relative to the moles of the transition metal in the catalyst complex. The reaction was then allowed to proceed until a pre-determined amount of pressure had been taken up by the reaction (typically 30 psig). Alternatively, the reaction may be allowed to proceed for a set amount of time. At this point, the reaction was quenched by pressurizing the vessel with compressed air. After the polymerization reaction, the glass vial insert containing the polymer product and solvent was removed from the pressure cell and the inert atmosphere glove box, and the volatile components were removed using a Genevac HT- 12 centrifuge and Genevac VC3000D vacuum evaporator operating at elevated temperature and reduced pressure. The vial was then weighed to determine the yield of the polymer product. The resultant polymer was analyzed by Rapid GPC (see below) to determine the molecular weight and by DSC (see below) to determine melting point.

Propylene polymerization (1 L autoclave conditions)

[0241] Supported catalyst (ca.0.5-0.6 g) was slurried into dry and degassed mineral oil to yield a slurry that contains 5% by weight of supported catalyst. The supported catalysts were added to the reactor as a slurry in oil (corresponding to 25 mg of solid catalyst). The catalyst slurry containing certain amounts of catalysts was injected using 250 mL propylene into a 1 L autoclave reactor containing propylene (300 mL) (total propylene 550 mL), optionally H2 (provided from a 25 mL container under the pressure) and triisobutylaluminum (TIBAL, 1.0 ml of a 5% toluene solution) were added at ambient temperature. The reaction was allowed to pre-polymerize for 5 minutes at room temperature. Subsequently, the reactor temperature was raised to about 70°C and the polymerization was run for an allotted period of time typically about 1 hour. After the allotted time the reactor was cooled to room temperature and vented, and polymer sample was collected and dried in vacuo overnight at 60°C.

RAPID GPC (used to characterize samples in TABLES B and C prepared with high throughput polymerization)

[0242] To determine various molecular weight related values by GPC, high temperature size 5 exclusion chromatography was performed using an automated“Rapid GPC” system as generally described in US Patent Nos.6,491,816; 6,491,823; 6,475,391; 6,461,515; 6,436,292; 6,406,632; 6,175,409; 6,454,947; 6,260,407; and 6,294,388, each of which is fully incorporated herein by reference for US purposes. This apparatus has a series of three 30 cm x 7.5 mm linear columns, each containing PLgel 10 mm, Mix B. The GPC system was calibrated using polystyrene standards ranging from 580 - 3,390,000g/mol. The system was operated at an eluent flow rate of 2.0 mL/minutes and an oven temperature of 165°C. 1,2,4-trichlorobenzene was used as the eluent. The polymer samples were dissolved in 1,2,4-trichlorobenzene at a concentration of 0.1 - 0.9 mg/mL.250 uL of a polymer solution was injected into the system. The concentration of the polymer in the eluent was monitored using an evaporative light scattering detector (as shown by the examples in Table 3) or Polymer Char IR4 detector. The molecular weights presented are relative to linear polystyrene standards and are uncorrected. GPC-DRI procedure (used to characterize samples in TABLE D, prepared in 1L autoclave)

[0243] M _w , M _n and M _w /M _n are determined by using a High Temperature Gel PermeationChromatography (Polymer Laboratories), equipped with a differential refractive index detector (DRI). Three Polymer Laboratories PLgel 10µm Mixed-B columns are used. The nominal flow rate is 1.0 mL/min, and the nominal injection volume is 300 µL. The various transfer lines, columns, and differential refractometer (the DRI detector) are contained in an oven maintained at 160°C. Solvent for the experiment is prepared by dissolving 6 grams of butylated hydroxytoluene as an antioxidant in 4 liters of Aldrich reagent grade 1, 2, 4 trichlorobenzene (TCB). The TCB mixture is then filtered through a 0.1 pm Teflon filter. The TCB is then degassed with an online degasser before entering the GPC instrument. Polymer solutions are prepared by placing dry polymer in glass vials, adding the desired amount of TCB, then heating the mixture at 160°C with continuous shaking for about 2 hours. AU quantities are measured gravimetrically. The injection concentration is from 0.5 to 2.0 mg/ml, with lower concentrations being used for higher molecular weight samples. Prior to running each sample the DRI detector is purged. Flow rate in the apparatus is then increased to 1.0 ml/minute, and the DRI is allowed to stabilize for 8 hours before injecting the first sample. The molecular weight is determined by combining universal calibration relationship with the column calibration which is performed with a series of monodispersed polystyrene (PS) standards. The MW is calculated at each elution volume with following equation.

where the variables with subscript“X” stand for the test sample while those with subscript “PS” stand for PS. In this method, aps =0.67 and Kps =0.000175 while ax and Kx are obtained from published literature, except that a/K = 0.695/0.000579 for ethylene polymers and 0.705/0.0002288 for propylene polymers. The concentration, c, at each point in the chromatogram is calculated from the baseline-subtracted DRI signal, IDRI, using the following equation:

where KDRI is a constant determined by calibrating the DRI, and (dn/dc) is the refractive 15 index increment for the system. Specifically, dn/dc = 0.109 for both PE and PP. The mass recovery is calculated from the ratio of the integrated area of the concentration chromatography over elution volume and the injection mass which is equal to the pre-determined concentration multiplied by injection loop volume. AU molecular weights are reported in g/mol unless otherwise noted. In event of 20 conflict between the GPC-DRI procedure and the "Rapid GPC," the GPC-DRI procedure above shall be used.

[0244] Melt flow rate (MFR)– Melt flow rate (MFR) was determined according to ASTM D1238 (230 ^C, 2.16 kg).

Differential Scanning Calorimetry (DSC-1, used for characterizing high throughput polymerization samples)

[0245] For the high throughput samples (described in Table B and C), the melting temperature (Tm) was measured using Differential Scanning Calorimetry (DSC) using commercially available equipment such as a TA Instruments TA-Q200 DSC. Typically, 5 to 10 mg of molded polymer or plasticized polymer is sealed in an aluminum pan and loaded into the instrument at about room temperature. Samples were pre-annealed at about 220°C for about 15 minutes and then allowed to cool to about room temperature overnight. The samples were then heated to about 220°C at a heating rate of about 100°C/min, held at this temperature for at least about 5 minutes, and then cooled at a rate of about 50°C/min to a temperature typically at least about 50°C below the crystallization temperature. Melting points were collected during the heating period.

Differential Scanning Calorimetry (DSC-2, used for characterizing samples prepared in 1 L autoclave)

[0246] Peak melting point, T _m , described for reactor batches (also referred to as melting point) and peak crystallization temperature, Tc, (also referred to as crystallization temperature) are determined using the following DSC procedure according to ASTM D3418-03. Differential scanning calorimetric (DSC-2) data can be obtained using a TA Instruments model DSC2500 machine. Samples weighing approximately 5 to 10 mg are sealed in an aluminum hermetic sample pan and loaded into the instrument at about room temperature. The DSC data are recorded by first gradually heating the sample to about 200°C at a rate of about 10°C/minute. The sample is kept at about 200°C for 5 minutes, then cooled to about -20°C at a rate of about 10°C/minute, followed by an isothermal for about 5 minutes and heating to about 200°C at about 10°C/minute, holding at about 200°C for about 5 minutes and then cooling down to about 25°C at a rate of about 10°C/minute. Both the first and second cycle thermal events were recorded. The melting and crystallization temperatures reported here were obtained during the second heating/cooling cycle unless otherwise noted. In the event of conflict between the DSC Procedure-1 and DSC procedure-2, DSC procedure-2 is used. NMR analysis of polymer samples

[0247] The propylene homopolymer or propylene copolymer produced herein may have some level of isotacticity, and can be isotactic or highly isotactic. As used herein,“isotactic” is defined as having at least 10% isotactic pentads according to analysis by ¹³ C NMR as described in US 2008/0045638 at paragraph [0613] et seq. As used herein,“highly isotactic” is defined as having at least 60% isotactic pentads according to analysis by ¹³ C NMR. In at least one embodiment, a propylene homopolymer having at least about 85% isotacticity, such as at least about 90% isotacticity can be produced herein. In another embodiment, the propylene polymer produced can be atactic. Atactic polypropylene is defined to be less than 10% isotactic or syndiotactic pentads according to analysis by ¹³ C NMR. Polymer microstructure can be determined by ¹³ C NMR spectroscopy, including the concentration of isotactic and syndiotactic diads ([m] and [r]), triads ([mm] and [rr]), and pentads ([mmmm] and [rrrr]). Samples were dissolved in deuterated tetrachloroethane (tce-d2) at a concentration of 67mg/mL at 140°C. Spectra were recorded at 120°C using a Bruker NMR spectrometer of 600MHz with a 10mm cryoprobe. A 90° pulse, 10 second delay, 512 transients, and gated decoupling were used for measuring the ¹³ C NMR. Polymer resonance peaks are referenced to mmmm = 21.98 ppm. Calculations involved in the characterization of polymers by NMR follow the work of Bovey, F. A. (19690 in "Polymer Conformation and Configuration" Academic Press, New York and Randall, J. (1977) in "Polymer Sequence Determination, 13C- NMR Method", Academic Press, New York. Table B– Propylene polymerization (High-throughput conditions)
