2-Ethylhexyl-methacrylates

Various substituted styrene-alkyl methacrylate block copolymers and all-acrylic block copolymers have been synthesized in a controlled fashion demonstrating predictable molecular weight and narrow molecular weight distributions. Table I depicts various poly (t-butylstyrene)-b-poly(t-butyl methacrylate) (PTBS-PTBMA) and poly(methyl methacrylate)-b-poly(t-butyl methacrylate) (PMMA-PTBMA) samples. In addition, all-acrylic block copolymers based on poly(2-ethylhexyl methacrylate)-b-poly(t-butyl methacrylate) have been recently synthesized and offer many unique possibilities due to the low glass transition temperature of PEHMA. In most cases, a range of 5-25 wt.% of alkyl methacrylate was incorporated into the block copolymer. This composition not only facilitated solubility during subsequent hydrolysis but also limited the maximum level of derived ionic functionality.

A 1 1 mixture of a carbodiimide containing latex polymer (t-butylcarbodiimidoethyl methylmethacrylate) and a carboxylic acid containing latex polymer (2-ethylhexyl methacrylate) showed that polymer interdiffusion occurs faster than crosslinking. Also, cyclohexylcarbodiimidoethyl methacrylate and t-butylcarbodiimidoethyl methacrylate have been prepared, and these monomers are used to prepare carbodiimide functionalized latex particles for emulsion polymerization. ... 

Combinations of benzophenone and tertiary amine groups, one of which was anchored to a polymer matrix, have also been checked in the photoinduced polymerization and photografting of 2-ethylhexyl methacrylate (EHMA) [52]. Indeed, poly(VBP-co-St)s, in the presence of 7V,Af-diethylaniline (DEA), are found to display lower photoinitiation activity and photografting efficiency than the corresponding copolymers of styrene with 4-(Af,Af-diethylamino) styrene [poly(St-co-DEAS)] in the presence of benzophenone (BP), as revealed by conversion and fractionation data (Table 10). 

AMS dimer was used to prepare a macromonomer of 2-ethylhexyl methacrylate. Copolymerization of the resulting macromonomer with butyl acrylate and acrylic acid gave a polymer backbone with Tg less than 10 °C that is useful in adhesive applications.486 The adhesive is better than the same composition made without the intermediacy of the macromonomer. 

Branched acrylic polymers based upon the copolymerization of acrylates and related monomers with methacrylate macromonomers are particularly useful in waterborne coatings. A macromonomer based upon isobutyl methacrylate, 2-ethylhexyl methacrylate, and 2-hydroxyethyl methacrylate was copolymerized with butyl acrylate, 2-hydroxyethyl acrylate, meth-acrylic acid, methyl methacrylate, and styrene.518 After neutralization with dimethylethanolamine or inorganic bases, the polymer could be cross-linked with melamine resin on a metal surface. These systems may be used for either pigmented layers or clear coats. 

Copolymerization of di- and trimethacrylates with functionalized monomers, like glycidyl methacrylate, leads to low-viscosity oligomers capable of nonradical cross-linking. This process promises substantial value for industrial applications. Star polymers useful in coatings were prepared by copolymerizing methacrylate macromonomers with diacrylates.519 For instance, a star polymer was synthesized by copolymerization of a 2-ethylhexyl methacrylate/isobutyl methacrylate/hydroxyethyl methacrylate macromonomer with butanediol diacrylate.

Oxygen Quenching in Poly(vinyl acetate) Particles. In order to study a system in which fluorescent groups could be Introduced into both the stabilizer and core polymers, we turned our attention to poly(vinyl acetate) [PVAc] particles sterically stabilized by poly(2-ethylhexyl methacrylate) [PEHMA] (14,15). Phenanthrene [Phe] was chosen as the fluorescence sensor. It was Introduced into the stabilizer by mixing a small amount (ca. 1%) of 9-phenanthrylmethyl methacrylate 1. with EHMA in the synthesis of PEHMA. It was introduced into the core polymer by mixing a trace (ca. 0.01%) of J with VAc in the presence of unlabelled PEHMA in the particle synthesis step.
