[034] The first component may include a cross-linker. The cross-linker may be employed for cross-linking the polymer and/or for forming a network structure. The cross-linker may be a compound that copolymerizes with the other monomers of the first component. For example, the cross-linker may include one or more (preferably two or more) alkene groups. Preferably, each alkene group is capable of polymerizing on a separate polymer molecules to form a link between the polymer molecules. As another example, the cross-linker may attach to a functional group (i.e., a functional group other than the alkene group) on each of two polymer molecules to connect the two polymer molecules. The cross-linker may be a multifunctional monomer, such as described herein.

Multifunctional Monomer

[035] The 1 , 1-disubstituted-1-alkene compound may include a multi-functional compound including two or more alkene groups. Examples of multi-functional compounds that may be employed herein include those described in U.S. Patent No. 9,249,265 B1 , issued February 2, 2016 (see e.g., column 9, line 12 through column 9, line 46), incorporated herein by reference in its entirety. Other examples of multi-functional compounds having a plurality of alkenyl groups includes those described in US Patent Application Publication US 2016/0068616 A1 (see e.g., paragraph 0042), incorporated herein by reference. For example, some or all of the 1 , 1- disubstituted alkenes can also be multifunctional having more than one core unit and thus more than one alkene group. Exemplary multifunctional 1 , 1-disubstituted alkenes are illustrated by the formula:

wherein R 1 , R 2 and X are as previously defined; n is an integer of 1 or greater; and R is a hydrocarbyl group, and the 1 , 1-disubstituted alkene has n + 1 alkenes.

[036] If employed, the amount of the multi-functional compound preferably is sufficiently low so that the glass transition temperature of the polymer is not greatly affected by the network structure formed by the cross-links formed upon polymerization. For example, any increase in the glass transition temperature due to the multi-functional compound preferably is about 50 °C or less. Preferably the amount of the multi-functional compound is about 50 weight percent or less, more preferably about 30 weight percent or less, and most preferably about 12 weight percent or less, based on the total weight of the 1 , 1-disubstituted-1-alkene compounds (e.g., in the polymerizable composition or in the grafted polymer). The amount of the multi-functional compound preferably is sufficiently high so that a network or other cross-linked structure is obtained and/or for accelerating the polymerization reaction. A network structure may be particularly useful in avoiding the grafted polymer from being entirely absorbed in water. Acceleration in the polymerization reaction may be particularly useful for reducing setting time of an adhesive or coating including the grafted polymer. The amount of the multi-function compound preferably is present in an amount of about 0.2 weight percent or more, more preferably about 0.5 weight percent or more, even more preferably about 1.5 weight percent or more, and most preferably about 3.6 weight percent or more, based on the total weight of the 1 , 1-disubstituted-1-alkene compounds.

Second Component

[037] Some or all of the 1 , 1-disubstituted-1-alkene compound (e.g., the 1 , 1-diester-1-alkene compound) is grafted with a second component that imparts hydrophilic characteristics to the grafted compound. The second component (i.e., the hydrophilic component) may be a water- soluble polymer or a functional compound having ionic characteristics. [038] Hydrophilic component may include an oligomeric polymer (e.g., having a molecular weight from about 200 g/mole to about 8500 g/mole) or a high molecular weight polymer (having a molecular weight greater than 8500 g/mole). Such polymer include polyacrylamide homopolymers and copolymers, polyvinyl alcohol hompolymers and copolymers, polyacrylic acid homopolymers and copolymers, polyalkoxide homopolymers and copolymers (e.g., polyethylene oxide), amine containing polymers (e.g., polyamines, polyethyleneimines, and polymers including quaternary ammonium compounds), copolymers of vinyl methyl ether and maleic anhydride, and polyvinylpyrrolidone homopolymers and copolymers.

[039] The second component may include or consist essentially of one or more quaternary ammonium com ounds, such as a salt having a cation with the following structure:

where the nitrogen is bonded to four carbon atoms. Preferably, the nitrogen atom is directly attached to one or more alkoxy groups. For example, the quaternary ammonium compound may have the structure: where X- is a counter anion. Preferably, R 1 , R 2 , R 3 , and R 4 are each alkyl or alkoxy groups, and most preferably d , C 2 , C 3 , or C 4 alkyl or d , C 2 , C 3 , or C 4 alkoxy groups. The number of alkoxy groups on the quaternary ammonium compound may be one, two or more, and is most preferably one.

[040] The counter anion for the quaternary ammonium compound may be any anion. Examples of anions include halogen anions (fluoride ion, chloride ion, bromide ion, or iodide ion), hydroxide ion, acetate ion, chlorate ion, sulfate ion, nitrate ion, perchlorate ion, and sulfite ion, nitrite ion, sulfate anions, sulfite anions, and carbonate ions. Particularly preferred anions include sulfite ions, nitrate ions, and carbonate ions.

Grafting or Transesterification Reaction [041] The second component may be grafted onto the 1 , 1-disubstituted-1-alkene compound (e.g., the 1 , 1-diester-1-alkene compound) using any method capable of connecting the compounds. Preferably the 1 , 1-disubstituted-1-alkene compound is directly connected to the second component by a covalent bond. A preferred reaction for grafting the second component is a transesterification reaction. The transesterification reaction may employ one or more catalysts. It will be appreciated that the grafting reaction may occur before or after the polymerization of the 1 ,1-disubstituted-1-alkene compound. Preferably the grafting reaction is performed prior to the polymerization reaction.

[042] An illustrative grafting reaction is shown below, where a 1 , 1-disubstituted-1-alkene compound (e.g., DEMM) is reacted with a quaternary ammonium salt by a transesterification

[043] Another illustrative grafting reaction is shown below, where a 1 , 1-disubstituted-1-alkene compound (e.g., DEMM) is reacted with a water-soluble polymer (e.g., polyethylene glycvol) by a transesterification reaction.

Catalyst

[044] The transesterification reactions according to the teachings herein are typically performed in the presence of one or more catalysts. The transesterification catalyst may be an acid, an ester of such acid or an enzyme. The transesterification catalyst may be an enzyme. The transesterification catalyst may be a lipase enzyme. A transesterification process utilizing an enzyme is disclosed in US 2014/0329980, incorporated herein by reference for all purposes in its entirety.

[045] The transesterification catalyst may be one or more acids having a pKa in a polar aprotic solvent of about -5 to about 14 or esters of the acids. The acid or the ester of the acid may be present in an amount of about 3.0 molar equivalents or less of the acid or the ester of acid per molar equivalent of the ester containing compounds transesterified. When the catalyst is an acid or an ester of an acid the method may be performed at a temperature of about 20 °C to about 160 °C. The transesterification catalyst may be a lipase enzyme catalyst. When the catalyst is a lipase enzyme catalyst the transesterification step is performed at an elevated temperature between about 20 °C and 70 °C. During the transesterification reaction, volatile byproducts may be formed and removed from the reaction mixture. The volatile by-products may be removed from the reaction mixture by applying a vacuum. The volatile by-products may be alcohols.

[046] The catalyst may be an acid or an ester thereof. The transesterification process using an acid or ester is disclosed in US Patent Application serial number 14/814,961 filed 07/31/2015, incorporated herein by reference for all purposes in its entirety. Any acid or ester thereof that catalyzes transesterification while minimizing side reactions may be used. In some embodiments the acid or acid utilized to form an ester is an acid having a pKa in a polar aprotic solvent, such as acetonitrile or dioxane, as disclosed hereinafter. In particular the pKa is chosen to efficiently catalyze the transesterification reaction while minimizing side reaction and the concentration of catalyst in a reaction mixture. The acid used may have a pKa of about -5 or greater, about -3 or greater, or about 1.0 or greater. The acid used may have a pKa of about 14 or less, about 11 or less, or about 9 or less. The acid can be a Bronsted acid having a pKa as disclosed. The catalyst may be a superacid or an ester thereof. Superacid means an acid having an acidic strength greater than the strength of 100 percent sulfuric acid. Ester thereof, in the context of the acid catalysts, refer to compounds wherein the hydrogen on the acid is replaced with a hydrocarbyl group, preferably an alkyl group. Superacids are acids having a strength greater than the strength of 100 percent sulfuric acid, a pKa less than 100 percent sulfuric acid, that is less than 8, more preferably less than about 5, and most preferably less than about 2. The measurement of acid strength is based on Kutt et al. "Equilibrium Acidities of Super Acids," Journal of Organic Chemistry Vol 76 pages 391 to 395, 201 1 , published on the Web December 17, 2010, which is incorporated herein by reference. Exemplary super acids include trifluoromethanesulfonic acid (triflic acid), sulfated tin oxide, inflated tin oxide, sulfated zirconia, triflated zirconia, and triflated HZSM-5. The most preferred super acids are triflic acid and fluorosulfonic acid.

[047] Exemplary acid catalysts include triflic acid, fluorosulfonic acid, and sulfuric acid. For reactions requiring monosubstitution (only one hydroxyl group on the alcohol is being replaced by transesterification), weaker acids with pKa values equal to or higher than sulfuric acid may be desired. Examples of such acids include sulfuric acid or methanesulfonic acid. For reactions requiring disubstitution (two hydroxyl groups on the alcohol are being replaced by transesterification), stronger acids with pKa values equal to or lower than sulfuric acid may be desired. Examples of such acids include sulfuric acid, fluorosulfonic acid, and triflic acid. For reactions requiring polysubstitution (more than 2 hydroxyl groups on the alcohol), choice of acid catalysts can be similar to that for disubstitution reactions but reaction time may need to be increased. Esters of acids useful as catalysts include alkyl triflates.

[048] The catalyst can be mixed with the reactants or can be supported on a substrate such as a membrane or an inert carrier such as a porous support structure (the catalysts can be heterogeneous). Catalysts which are not supported are commonly referred to as homogeneous. The catalyst can be used in any concentration that catalyzes the transesterification reaction. The amount of catalyst utilized for the reaction depends on the type of catalyst being chosen. The concentration of catalyst is about 3 molar equivalents or less per equivalent of the ester compounds undergoing transesterification; about 1 molar equivalents or less; about 0.5 molar equivalents or less; about 0.1 molar equivalents or less. The concentration of catalyst is about 0.01 molar equivalents or greater per equivalent of the ester compounds undergoing transesterification; and most preferably about 0.1 molar equivalents or greater. Higher concentrations of catalysts than recited may be utilized. As disclosed in Malofsky et al., US 8,609,885 and 8,884,051 ; and Malofsky et al. WO 2013/059473 the presence of acid in the 1 , 1- disubstituted alkene compounds recovered can present problems with respect to use of the compounds and low concentrations of acid in the products in use is desired. If high levels of acid are contained in the final product, additional purification or removal steps may be required. The amounts recited achieve the balance between efficient catalysis and the need for low acid concentrations in the product for use. In embodiments when the catalyst is selected from sulfuric acid or those acids having pKa values less than that of sulfuric acid, the concentration of such catalysts in the reaction mixture is preferably at the upper end of the ranges recited herein.

[049] The catalyst may include or consist entirely of an enzymatic catalyst. Any enzymatic catalyst suitable for catalyzing the transesterification reaction may be used. Various enzymatic catalysts are described in US Patent 7,972,822 B2 (by Gross et al., issued on July 5, 2011 , see for example column 8, lines 2-4 and 7-35), US Patent 5,416,927 A (by Zaks et al., issued May 31 , 1994, see for example column 2, line 64 to column 3, line 12), US Patent 5,288,619 A (by Brown et al., issued February 22, 1994, see for example column 4, line 18 to column 5, line 17), US Patent Application Publication 2016/177,349 A1 (by Addy et al., published June 23, 2016, see for example paragraphs 0046 - 0048), U.S. Patent Application Publication 2014/0017741 A1 (by Nielsen et al., published Jan. 16, 2014, see for example paragraphs 0026-0029); the contents of which are each incorporated herein by reference. [050] Many different enzymes may be employed in enzymatic catalytic transesferification reactions for wax esters, including those that are derived/obtained from biological organisms, those made synthetically, and those that are entirely artificial, whether made biologically and/or synthetically. For those enzymes that are lipases, these may include, one, some, any, or any combination of lipases derived from the following organisms: Aspergillus niger, Aspergillus oryzae, Bacillus subtilis, Bacillus thermocatenuiafus, Burkholderia cepacia, Burkholderia glumae, Candida rugosa, Candida antarctica A, Candida antarctica B, Candida cyiindracea, Candida parapsiiosis, Chromohacterium viscosum, Geotrichum candidum, Geotrichum sp., Mucor miehei, Humico!a lanuginosa, Peniciilium camemhertii, Peniciiiium chrysogenum, Peniciilium roquefortii, Pseudomonas cepacia, Pseudomonas aeruginosa, Pseudomonas fluorenscens, Pseudomonas frags, Pseudomonas aicaligenes, Pseudomonas mendocina, Rhizopus arrhizus, Rhizomucor miehe, Staphylococcus hyicus, Staphylococcus aereus, Staphylococcus epidermidis, Staphylococcus warneria, Staphylococcus xylosus, Thermomyces lanuginosus, Aspergillus sp., Bacillus sp., Burkholderia sp., Candida sp., Chromobacterium sp., Geotrichum sp, Mucor sp, Humicola sp, Peniciilium sp, Pseudomonas sp, Rhizopus sp., Staphylococcus sp, and Thermomyces sp.

Polymerization of the grafted 1 , 1-disubstitufed-1-a!kene [051] The grafted 1 , 1-disubstituted-1-alkene compound may be polymerized by reacting the alkene group onto a growing polymer chain. Preferably about 70% or more, even more preferably about 90 % or more, and most preferably about 98% or more of the alkene groups are polymerized. Preferably, the polymer includes a sufficient amount of the hydrophilic component (e.g. the water-soluble polymer and/or the cation containing compound) so that the resulting grafted polymer is hydrophilic or water-soluble. The polymerization reaction may be catalyzed (e.g., using tetramethylguanidine).

[052] The polymerization of a grafted 1 , 1-disubstituted alkene including a water-soluble polymer is illustrated below.

Hydrophilic polymers

[053] The polymerization of a grafted 1 , 1-disubstituted alkene including a cation containing compound is illustrated below. WATER SOLUBLE POLYM ER

[054] The polymerization reaction may occur at one or more reaction temperatures sufficiently high for converting the monomer into polymer. As the polymerization reaction progresses, the polymerizable composition may become a viscous liquid, a glassy liquid (e.g., below the glass transition temperature of the polymer) or even a solid (e.g., below the melting temperature of the polymer). Preferably, the reaction temperature is above the glass transition temperature of the resulting polymer (e.g., of the first component). Preferably, the reaction temperature is above any melting temperature of the resulting polymer. As an alternative, the process may include an initial polymerization at a relatively low temperature (e.g., below any melting temperature and/or below the glass transition temperature of the polymer) and then the process may include a secondary polymerization reaction at a higher temperature (e.g., above the melting temperature and/or above the glass transition temperature of the polymer). The reaction temperature and reaction time may be selected to provide a desired level of polymerization and/or a desired level of cross-linking.

Polymerizable system (i.e., polymerizable composition) [055] One aspect according to the teachings herein, is directed at a polymerizable system including the grafted 1 ,1-disubstituted alkene compound (e.g., grafted with the quaternary ammonium compound or with a water-soluble polymer) and preferably further including one or more 1 , 1-disubstituted alkene compounds (e.g., a methylene malonate monomer) that is free of any such graft The methylene malonate monomer may be selected so that it will copolymerize with the alkenyl groups of the grafted compound. It will be appreciated that the grafted compound may include a 1 , 1-disubstituted-1 -alkene compound that is the same or different from the methylene malonate monomer.

[056] Any of the methylene malonate compounds described herein with respect to the graft compound having an alkenyl group for the may be employed as an additional monomer in the polymerizable composition. It will be appreciated that methylene malonate monomer may be replaced in part or in whole with dimers, trimers, or longer oligomers (e.g., having a degree of polymerization of about 4 to 50, about 4 to 15, or about 4 to 8).

[057] The polymerizable system may include a sufficient amount of a stabilizer to prevent or minimize polymerization of the polymerizable system. The process may include a step of activating the polymerizable system for polymerizing the methylene malonate monomers and alkenyl group(s) attached to the grafted compound.

[058] It will be appreciated that the polymerizable system may be used to form a grafted polymer that is a block copolymer including a first block including one or more 1 , 1-disubstituted alkene compounds and a second block including the water-soluble polymer. The amount of the first polymer block preferably is about 10 weight percent or more, more preferably about 20 weight percent or more, even more preferably about 25 weight percent or more, and most preferably about 30 weight percent or more, based on the total weight of the block copolymer. The amount of the first block may be about 90 weight percent or less, about 80 weight percent or less, about 70 weight percent or less, about 60 weight percent or less, or about 50 weight percent or less, based on the total weight of the block copolymer.

[059] The amount of the water-soluble polymer in the block copolymer preferably is about 10 weight percent or more, more preferably about 20 weight percent or more, even more preferably about 30 weight percent or more, even more preferably about 40 weight percent or more, and and most preferably about 50 weight percent or more, based on the total weight of the block copolymer. The amount of the water-soluble polymer may be about 90 weight percent or less, about 80 weight percent or less, about 75 weight percent or less, or about 70 weight percent or less, based on the total weight of the block copolymer. The ratio of the weight of the first component to the weight of the water-soluble polymer in the block copolymer may be about 0.05 or more, about 0.10 or more about 0.20 or more or about 0.45 or more, or about 0.60 or more. The ratio of the weight of the first component to the weight of the water-soluble polymer may be about 10 or less, about 8 or less, about 6 or less, about 4 or less, about 3 or less, or about 2 or less.

[060] The grafted 1 , 1-disubstituted alkene compounds and/or polymerizable system may be used for a film or coating. The film or coatings may have a thickness of about 0.001 μηι or more, about 0.1 μηι or more, about 1 μηι or more, or about 2 μηι or more. The coating or film preferably has a thickness of about 200 μηι or less, more preferably about 50 μηι or less, and most preferably about 20 μηι or less.

[061] The grafted polymer may be used in a polymeric composition including about 10 weight percent or more of the grafted polymer and about 0.5 to about 90 weight percent of one or more compounds selected from the group consisting of a filler, a stabilizer, a process aid, a biocide, a polymer, a colorant, a salt, and any combination thereof. For example, the polymeric composition may include a sufficient amount of a salt so the polymeric composition is an electrical conductor.

[062] The second component may impart useful characteristics to the 1 , 1-disubstituted alkene compound (or the resulting grafted polymer) for use in oil field applications. For example, the grafted compound may be used as an oil-wetting agent, a bactericide, or a corrosion inhibitor.

[063] The compositions, compounds and grafted polymers according to the teachings herein may be employed in various applications that take advantage of feature of one or both of the components of the grafted polymer. In particular, these materials may be employed in electronics (conducting polymers), as a surfactant, an ionomer, in a pharmaceutical process, in petroleum recovery in water treatment, as a flocculant, in a hydrometallurgy process, or as a detergent. Other applications include as a hydrophilic coating. For example, such a coating may be useful for anti-fouling applications. Without being bound by theory, it is believed that the high amount of hydration may provide a surface difficult for proteins and microorganisms to attach to. As such, the materials according to the teachings herein may prevent or reduce the accumulation of bio-organisms on a surface. These may be used for protecting against fouling by plants, algae, microorganisms, or animals. The material and compositions according to the teachings herein may be particularly used on surfaces that are at least partially submerged in a body of water containing organisms capable of fouling or otherwise attaching to the surface. They may be used for preventing fouling by calcerous fouling organisms include mussels (e.g., zebra mussels), mollusks, barnacles, and other organisms that form a hard calcium carbonate containing structure. They may be used for preventing fouling by non-calcerous organisms include algae, biofilm, seaweed and other organisms that lack a calcium carbonate containing structure. The materials and compositions according to the teachings herein may be used for removing water from surfaces and/or for keeping surfaces dry. The materials and compositions according to the teachings herein may be used for converting liquid waste to a stable solid or other structure where the liquid is absorbed by the grafted polymer. This may be particularly useful where the liquid includes chemically hazardous compounds, biologically hazardous materials, toxic materials, or environmentally hazardous substances.

[064] Any numerical values recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51 , 30 to 32 etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001 , 0.001 , 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. As can be seen, the teaching of amounts expressed as "parts by weight" herein also contemplates the same ranges expressed in terms of percent by weight. Thus, an expression in the Detailed Description of the Invention of a range in terms of at " x parts by weight of the resulting polymeric blend composition" also contemplates a teaching of ranges of same recited amount of "x" in percent by weight of the resulting polymeric blend composition." [065] Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of "about" or "approximately" in connection with a range applies to both ends of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30", inclusive of at least the specified endpoints.

[066] The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The term "consisting essentially of" to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination.

EXAMPLES

[069] Example 1

[070] Example 1 is a reaction mixture including a methylene malonate monomer grafted with a polyalkylene glycol and unreacted methylene malonate monomer. The grafting reaction is carried out using PEGylation process.

[071] CARBOWAX™ PEG 300 polyethylene glycol (commercially available from DOW CHEMICAL COMPANY) is purified by passing through an alumina column to residual base catalyst. The polyethylene glycol has a number average molecular weight of about 285 to 300 g/ mole, a hydroxyl number of about 340 to 394 mg KOH/g, a melting range of about -15°C to about -8 °C, and a heat of fusion of about 37 cal/g. A 250 mL round bottom flask is charged with about 30 g (0.17 mol) of DEMM, about 3 g (10wt % of the DEMM) of CLEA 102B4enzyme and about 16.6 g (0.083 mol) of the PEG 300 (alumina passed). The flask is connected to a rotary evaporator with a vacuum of about 200 mm Hg and heated to about 45 °C for 2 hrs. The vacuum removes ethanol as a reaction by-product. The enzyme is then filtered from the reaction mixture using a cotton plug in 20 ml syringe. NMR results indicate that about 35 percent of the DEMM is reacted to the PEG and about 65 percent of the DEMM remains as unreacted monomer in the reaction mixture. FIG. 1 shows the NMR for the reaction mixture. [072] The grafted DEMM may have a structure including a central polymer portion including a polyalkoxide and terminal methylene malonate groups having one or more (or all) of the features illustrated below:

[073] The reaction mixture of the grafted DEMM is drawn down on a pre-initiated (0.1 % Na- benzoate in butyl cellosolve) cold rolled steel panel using a Meyer Rod 10 resulting in a 25- micron thick coating after full cure at room temperature for 24 hours followed by heating at 82°C for 1 hour. The coating displays hydrophilic character with water wetting the surface with ease and eventually permeating through the coating layer on continued exposure. A similar coating drawn down with only DEMM monomer demonstrates no hydrophilic character. This demonstrates the hydrophilicity imparted by polyethylene glycol in DEMM based coatings.

[074] Example 2

[075] Example 2 is a reaction mixture including a polyalkylene glycol grafted onto a methylene malonate monomer and unreacted methylene malonate monomer. The grafting of the polyalkylene glycol is carried out using an acid catalyzed transesterification process.

[076] A three neck (250 ml_) round bottom flask with a distillation head, thermometer, vacuum adapter, and a collection flask are assembled using high vacuum grade grease along with a heating mantle (and thermocouple) and a magnetic stir bar. To this round bottom flask set-up, a mixture of about 20 g (about 0.12 mol) of DEMM, about 4.6 g (about 0.023 mol) of CARBOWAX™ PEG 200 polyethylene glycol (commercially available from DOW CHEMICAL COMPANY), about 0.02 g (about 1000 ppm) of MeHQ and about 0.3 ml (about 0.0058 mol) of H 2 S0 4 is charged. CARBOWAX™ PEG 200 polyethylene glycol has a weight average molecular weight of about 190 to 210 g/mole, an average hydroxyl number of about 535 to about 590 mg KOH/g, and a melting point below about -65 °C. A reduced pressure of about 400 mm Hg is maintained during the reaction using a vacuum pump. The reaction mixture is then heated to about 130 °C and stirred for about 2 hours. Ethanol is collected as a reaction byproduct. The amount of grafting of the PEG onto the DEMM is calculated using NMR. About 45 percent of the DEMM is reacted with the PEG and about 55 percent of the DEMM remains as monomer. [077] The grafted compound may have a structure including a central polymer portion including a polyalkoxide and terminal methylene malonate groups having one or more (or all) of the features illustrated below:

[078] Example 3

[079] Example 3 is a reaction mixture including a glycerol ethoxylate grafted onto a methylene malonate monomer and unreacted methylene malonate monomer. The grafting of the glycerol ethoxylate may be carried out using a transesterification process.

[080] A 250 ml_ round bottom flask is charged with about 30 g (about 0.17 mol) of DEMM, about 3 g (about"! 0 parts per 100 parts of DEMM) of enzyme NOVOZYME 435 Candida antartica isoform B (commercially available from NOVOZYME) and about 56 g (about 0.056 mol) of glycerol ethoxylate (having a number average molecular weight of about 1000, obtained from Sigma Aldrich). The flask is connected to a rotary evaporator with reduced pressure of about 200 mm Hg and is heated to about 55 °C for about 8 hours. Ethanol is removed as a reaction byproduct. The enzyme is then filtered from the product using cotton plug in a 20 ml syringe, for isolating the reaction mixture. NMR results are obtained of the reaction mixture and used to calculate the conversion of the glycerol ethoxylate to the end-capped product. About 40% of desired transesterified products (i.e., end-capped product) is observed. The NMR spectrum for the reaction mixture is shown in FIG. 2. It is believed that the reaction mixture includes disubstituted and trisubstituted glycerol ethoxylate reaction products. The resulting reaction mixture includes the grafted compound having one or more of the features as shown in the structures below.

[081] The reaction mixture is drawn down on a pre-initiated (0.1 % Na-benzoate in butyl cellosolve) cold rolled steel panel using a Meyer Rod 10 resulting in a about 25-micron thick coating after full cure at room temperature for about 24 hours followed by heating at about 82°C for about 1 hour. The coating displays hydrophilic character with water wetting the surface with ease and eventually permeating through the coating layer on continued exposure. In comparison, a specimen prepared with the reaction mixture replaced with only DEMM and cured under the same conditions (e.g., resulting in a DEMM homopolymer) demonstrates no hydrophilic character. Thus, the DEMM grafted with glycerol ethoxylate may be used to impart hydrophilicity in a coating (e.g., in a methylene malonate coating, such as a DEMM based coatings).

[082] Characterization of the Graft Polymer

[083] The graft polymer may be evaluated for water solubility / hydrophilicity characteristics.

[084] A primer solution of either about 0.1 wt % sodium benzoate or about 0.5 wt % tetramethylguanidine (i.e, TMG) in ethanol is drawn down onto a steel panel using a meyer rod. The solvent is allowed to flash off at room temperature. Then, 2ml of a polymerizable composition (e.g., including the second component directly attached to a methylene malonate compound) is applied to the top of the panel and drawn down in a similar manner using a meyer rod. The coating is left to cure at room temperature overnight for about 18 hours.

[085] The cured coating is tested by applying a single drop of reverse osmosis (i.e., RO) water to the surface and measuring the amount of time for the coating to be dissolved or the drop to be absorbed. The coating displays hydrophilic character with water wetting the surface of the coating with ease and eventually permeating through the coating layer and preferably removing the coating on continued exposure.

[086] Several graft polymers are prepared by mixing a dimethyl methylene malonate monomer, diethyl methylene malonate functionalized with glycerol ethoxylate, and a cross-linker as shown in the table below and coatings were tested in the following manner. The polymerization is on the steel substrate treated with the primer solution as described above.

[087] After polymerizing the first component, the first component includes a random copolymer of the D3M, DEMM, and the cross-linker, where the cross-linker is a multi-functional 1 , 1- disubstituted-1-alkene compound having a plurality of polymerizable alkene groups. The second component (i.e, the hydrophilic component) consists essentially of the glycerol ethoxylate.

[088] After curing overnight at room temperature, the time for the drop of water to solubilize the coating is measured. As the amount of cross-linker is increased, the time for solubilizing the coating is increased.

[089] Samples are also prepared, as described above, except the coating is exposed to a secondary cure by heating for about 30 minutes at a temperature of about 80 °C. After the secondary cure, the time for solubilizing the coating is increased.
