Abstract:
A thermally stable, extrudable curable elastomer composition comprisinga) 75 to 95 weight percent of an elastomer selected from the group consisting of 1) copolymers comprising ethylene and a comonomer selected from the group consisting of C1-C8 alkyl esters of acrylic acid, C1-C8 alkyl esters of methacrylic acid, and vinyl esters of C2-C8 carboxylic acids; 2) alkyl acrylate polymers selected from the group consisting of homopolymers of C1-C10 alkyl acrylates and copolymers of C1-C10 alkyl acrylates with up to 40 weight percent monovinyl monomers; and 3) diene copolymers selected from the group consisting of copolymers of a diene and an unsaturated nitrile and hydrogenated copolymers of a diene and an unsaturated nitrile; b) 2 to 24 weight percent of a multifunctional crosslinking agent selected from the group consisting of multifunctional acrylic crosslinking agents, multifunctional methacrylic crosslinking agents, multifunctional cyanurate crosslinking agents, and multifunctional isocyanurate crosslinking agents; and c) 0.2 to 5.0 weight percent of a UV initiator wherein the weight percentages of each of a), b), and c) are based on the combined weight of components a), b), and c).
