Description:
PATENT Attorney Docket No.: 27178.106PCT ACRYLIC STRUCTURAL ADHESIVES AND METHODS FOR MAKING SAME CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 63/414,945, filed October 11, 2022, which is incorporated herein by reference in its entirety. BACKGROUND Field [0002] Provided herein are acrylic structural adhesives that are made from high vinyl content styrene-butadiene-styrene block copolymers and acrylate monomers, such as methyl methacrylate. Description of the Related Art [0003] Structural adhesives are substances that adhere or fasten together structural elements to produce high modulus, high strength, permanent chemical bonds. They are good alternatives to other mechanical techniques for binding two materials together, such as metals or plastics. They have better force distribution through their chemical bonding compared to other techniques, such as riveting or welding. In addition, chemical bonding can allow for more rapid working and can provide better insulation from external elements, such as dust and moisture, than other mechanical means. Hence, structural adhesives are used in many industrial fields. However, structural adhesives can have disadvantages. For example, the chemical bonding formed during the curing of the structural adhesive can often be too rigid, especially when good mechanical strength is needed. In such situations, the structural adhesives can fracture, separating the structural elements. [0004] Consequently, there is a need for new structural adhesives that can provide good mechanical strength while maintaining effective elasticity. SUMMARY [0005] Disclosed herein are acrylic structural adhesives that include a high vinyl content styrene-butadiene-styrene block copolymers and acrylate monomers. In a specific embodiment, the acrylic structural adhesive includes: an acrylic monomer; a vinyl styrenic block copolymer, where the vinyl styrenic block copolymer includes a vinyl content of greater than 50 wt%; a curing agent; and an additive. [0006] In another specific embodiment, the acrylic structural adhesive includes: a methyl methacrylate monomer; a vinyl styrenic block copolymer, where the vinyl styrenic block copolymer as a Formula selected from: α-V-D-ω (I), d-V-D-ω (II), α-V ° -D-V′-ω (III), and d- V ° -D-V′-ω (IV), where the vinyl content of the block copolymer is at least 50%; a benzoyl peroxide; and an additive. 1 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT [0007] In another specific embodiment, the method of making an acrylic structural adhesive includes: contacting a viny styrenic block copolymer and a (meth) methacrylic monomer to make a first mixture, where the vinyl styrenic block copolymer a Formula selected from: α-V- D-ω (I), d-V-D-ω (II), α-V ° -D-V′-ω (III), and d-V ° -D-V′-ω (IV), where the vinyl content of the block copolymer is at least 50%; contacting an additive with the first mixture to make a second mixture; contacting a curing agent to make a third mixture; and mixing the second and third mixtures to make the acrylic structural adhesive.

[0018] The one or more polyvinyl aromatic blocks can include, but are not limited to: three or more mer units deriving from the polymerization of vinyl aromatic monomer. The vinyl aromatic monomer can include, but are not limited to: styrene, α-methyl styrene, p- methylstyrene, and vinylnaphthalene. In an embodiment, polydiene blocks include three or more mer units deriving from the polymerization of conjugated diene monomer. In another embodiment, polydiene blocks include three or more mer units deriving from the polymerization of a non-conjugated diene monomer. Examples of a conjugated diene monomer can include, but are not limited to: 1,3-butadiene; isoprene; 1,3-pentadiene; 1,3- hexadiene; 2,3-dimethyl-1,3-butadiene; 2-ethyl-1,3-butadiene; 2-methyl-1,3-pentadiene; 3- methyl-1,3-pentadiene; 4-methyl-1,3-pentadiene; 2,4-hexadiene; and mixtures thereof.

In an embodiment, the D of Formula I can be characterized by a vinyl content of less than about 100%, less than about 95%, less than about 90%, less than about 85%, or less than about 80%. The vinyl content may be determined by 1 H NMR, and as reported herein refers to the percentage of mer units positioned in the 1,2-microstructure based on the total mer units deriving from the polymerization of conjugated diene monomer. 4 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT [0020] In an embodiment, the D block of Formula I can include at least about 250, at least about 350, at least about 450, and at least about 550 mer units deriving from the polymerization of conjugated diene monomer.

[0027] In an embodiment, the vinyl styrenic block copolymer can be defined by the Formula III: α-V ° -D-V′-ω (III), where each V is independently a polyvinyl aromatic block, D is a polydiene block, α and ω are each independently a hydrogen atom, a functional group, or a polymeric segment or block, and where D is characterized by a vinyl content of at least 50%. [0028] In an embodiment, D of Formula III can be characterized by a vinyl content (i.e. the percentage of mer units positioned in the 1,2-microstructure) of at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, and at least 85%.

In an embodiment, the ratio of V ° mer units to V′ mer units can be less than about 4:1, less than about 3:1, less than about 2:1, than 1.5:1, less than about 1.1:1, and less than about 1.05:1. In an embodiment, the ratio of V ° mer units to V′ mer units can be about 1:1.

In an embodiment, the blocks of the vinyl styrenic block copolymer defined by the Formula III can be substantially devoid of tapering, which includes that amount of tapering or less that will not have an appreciable impact on the block copolymer. In an embodiment, the blocks of the vinyl styrenic block copolymer defined by the Formula III can be devoid of tapering. [0033] In an embodiment, the vinyl styrenic block copolymer of Formula III is a diene block, and therefore the block copolymer can be defined by the Formula IV: d- V ° -D-V′-ω (IV), where d is a polydiene block, V ° , V′, D, and ω are as defined above with respect to Formula III, and where D and d are characterized by a vinyl content of at least 50%. [0034] In an embodiment, d of Formula IV can be characterized by a vinyl content (i.e. the percentage of mer units positioned in the 1,2-microstructure) of at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, and at least 85%. In an embodiment, d of Formula IV can be characterized by a vinyl content of less than about 100%, less than about 95%, less than about 90%, less than about 85%, and less than about 80%. [0035] In an embodiment, d of Formula IV includes at least 10, least 40, at least 60, and at least 80, at least 100, and at least 120 mer units deriving from the polymerization of conjugated diene monomer. In an embodiment, d of Formula IV includes less than about 500, less than about 350, less than about 250, less than about 200, less than about 180, less than about 160, and less than about 120 mer units deriving from the polymerization of conjugated diene monomer. [0036] In an embodiment, the overall vinyl content of the block copolymers of the present invention can be at least 50%, in other embodiments at least 55%, in other embodiments at least 60%, in other embodiments at least 65%, in other embodiments at least 70%, in other embodiments at least 75%, in other embodiments at least 80%, and in other embodiments at least 85%. In these or other embodiments, d of Formula IV is characterized by a vinyl content of less than 100%, in other embodiments less than 95%, in other embodiments less than 90%, in other embodiments less than 85%, and in other embodiments less than 80%. The overall 7 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT vinyl content of the block copolymers can be tailored by adjusting the vinyl content of particular diene blocks. For example, where the block copolymers are defined by the Formulae II and IV, the vinyl content of the d block can be increased, without necessarily providing a corresponding increase to the D block, to affect an overall increase in the vinyl content of block copolymer. [0037] In an embodiment, the blocks of the vinyl styrenic block copolymer defined by the Formula IV include less than about 5%, less than about 3%, less than about 1%, and less than about 0.5% tapering in any given block of the vinyl styrenic block copolymer.

In an embodiment, the overall peak molecular weight of the vinyl styrenic block copolymer can be less than about 150 kg/mole, less than about 125 kg/mole, less than about 100 kg/mole, and less than about 90 kg/mole. [0039] In one or more embodiments, the method of making the vinyl styrenic block copolymer can include a polymerization reaction. For example, the method of making the vinyl styrenic block copolymer can be performed in solution, which includes those polymerization mediums where the monomer to be polymerized can be dissolved in a solvent. In an embodiment, the polymer that is synthesized according to the method can also be soluble in the solvent. [0040] The polymerization can be carried out as a batch process, a continuous process, or a semi-continuous process. In an embodiment, conditions can be controlled to perform the polymerization under a pressure of from about 10,132.5 Pa (0.1 atmosphere) to about 5.066 x 10 6 Pa (50 atmospheres), about 50,662.5 Pa (0.5 atmospheres) to about 2.066 x 10 6 Pa (20 atmospheres), or about 101,325 Pa (1 atmosphere) to about 1.013 x 10 6 Pa (10 atmospheres). In an embodiment, the polymerization mixture may be maintained under anaerobic conditions. [0041] The one or more acrylic structure adhesives can include one or more vinyl styrenic block copolymers with a vinyl content that varies widely. For example, the one or more acrylic structure adhesives can include one or more vinyl styrenic block copolymers with a vinyl content from a low of about 45 wt%, about 50 wt%, or about 55 wt%, to a high of about 75 wt%, about 85 wt%, or about 95 wt%.

In another example, the one or more acrylic structure adhesives can include one or more vinyl styrenic block copolymers with vinyl content from about 49 wt% to about 95 wt %, about 25 wt% to about 35 wt%, about 47 wt% to about 51 wt %, about 49 wt% to about 53 wt %, about 50 wt% to about 61 wt %, about 55 wt% to about 68 wt %, about 51 wt% to about 88 wt %, about 55 wt% to about 76 wt %, or about 65 wt% to about 92 wt %. The weight percent of the vinyl in the vinyl styrenic block copolymers can be based on the total weight of the vinyl styrenic block copolymer; or based on the total weight of the vinyl mer units and the styrene mer units.

[0073] In one or more embodiments, the acrylic structural adhesives can be used for wide variety of applications. For example, the acrylic structural adhesives can be used in insulating packer fluids, fluid loss pills, drilling fluids, and completion fluids. In one or more embodiments, using the acrylic structural adhesives in a drilling fluid or a completion fluid can include, but is not limited to: injecting an acrylic structural adhesive into a wellbore or injecting the acrylic structural adhesive into a subterranean formation. In another example, the acrylic structural adhesives can be made into thixotropic fluids and/or cohesive gels. In another example, the acrylic structural adhesives can be used with the compositions and methods discussed in U.S. Patent No. 9,657,213, U.S. Patent No. 10,053,609, and U.S. Patent No. 11,692,048, each of which is incorporated herein by reference in its entirety. EXAMPLES [0074] To provide a better understanding of the foregoing discussion, the following non- limiting examples are offered. Although the examples can be directed to specific embodiments, they are not to be viewed as limiting the invention in any specific respect. [0075] Methyl methacrylate was mixed with STEREON® 8983 at 7:3 ratio in closed reaction vessel. A mixer was used to mix at 2,150 rpm for 30 minutes. 2% Benzoyl peroxide was then added and mixed for additional 10 min. To prevent evaporation of methyl methacrylate monomer, the mixture was pre-cured in 60°C water bath for 15 minutes. Magnetic stirring was at 260 rpm to well disperse sample. To eliminate bubbles formed during pre-curing, sample was mixed again by mixer at 2,150 rpm for 20 minutes. [0076] The acrylic structural adhesive was cured by heat press to measure tensile properties. The sample was cured at elevated temperature for 90 min. Curing temperature was initially set at 75 °C for 30 min, then increased to 95 °C and 120 °C for 30 minutes. Dumbbell samples were cut from cured sample slab to conduct tensile tests with 50 mm/min crosshead rate. [0077] STEREON® 8983 (79% vinyl)/methyl methacrylate adhesive (group A) had higher tensile strength, elongation at break and elastic modulus than KRATON® 1101 (15% vinyl)/methyl methacrylate adhesive (group B) and KRATON® 1192 (43% vinyl) /methyl methacrylate adhesive (group C). [0078] Initial efforts to demonstrate this invention resulted in adhesive formulations that contained a lot of bubbles that created defects in the cured adhesive, as shown in FIGURE 1. These problems were overcome in the following example. [0079] The pre-polymerization and mixing time were further adjusted to well disperse STEREON® 8983 in methyl methacrylate. Increasing pre-polymerization time from 15 19 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT minutes to 20 minutes caused some bubbles before curing, because bubbles were difficult to be eliminated in liquid sample with high viscosity. So, pre-polymerization time was maintained at 15 minutes. Mixing time was increased from 10 minutes to 20 minutes, and undispersed methyl methacrylate dots disappeared, as shown in FIGURE 2. [0080] In one experiment, three inventive examples of the structure adhesive compositions using different concentrations of monomers and copolymers were made to determine the effect on the strength properties of the adhesive. In a first example (Ex 1), SB 8983 was used to make the structure adhesive composition. In a second example (Ex 2), KRATON® 1101 was used to make the structure adhesive composition. In a third example (Ex 3), 25 wt % of the vinyl styrenic block copolymer, STEREON® 8983, and 5 wt% of vinyl norbornene TRILENE® was used to make the structure adhesive composition. The strength properties of these three structural adhesives are shown in Table 1. Table 1: Acrylic Structural Adhesive Strength Properties t [008 gth and elongation at break than KRATON® 1101/methyl methacrylate compositions. Since both SB copolymers had about 30 wt% of styrene, the different tensile performance can be related to high vinyl content of STEREON® 8983. The tensile strength and elongation at break were similar as the formulation without TRILENE®. Some small bubbles on cured slab may have detrimental effects on tensile properties. The small bubbles may be related to slow polymerization rate caused by addition of TRILENE®. [0082] In another experiment, five more acrylic structural adhesives (Ex A, Ex B, Ex C, Ex D, and Ex E) using different concentrations of monomers and copolymers were made. The reaction conditions and resulting properties are shown in Tables 2-6. The substrate is aluminum. 20 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT Table 2: Acrylic Structural Adhesive Reaction Conditions Table 3: Acrylic Structural Adhesive Compositions a e : ens e erormance o te cry c tructura esive Table 5: Acrylic Structural Adhesive Physical Properties n] 21 4868-9670-1574 v.8 PATENT Attorney Docket No.: 27178.106PCT Table 6: Acrylic Structural Adhesive Physical Properties e [ late structural adhesive formulation improved cure time.
