Claim:
1. A blend composition of ethylene vinyl acetate copolymer, peroxide curable polyacrylate elastomer, and polyamide, said blend composition consisting of (A) from about 10 wt % to about 98 wt % of an ethylene vinyl acetate copolymer component said ethylene vinyl acetate copolymer component comprising one or more ethylene vinyl acetate copolymers of at least 40% by weight copolymerized vinyl acetate monomer units; (B) from about 1 wt % to about 50 wt % of a one or more of peroxide curable polyacrylate elastomer component comprising copolymerized units of alkyl acrylate, and at least 0.03 mol % of copolymerized units of an amine or acid reactive monomer selected from the group consisting of unsaturated carboxylic acids, anhydrides of unsaturated carboxylic acids, and unsaturated epoxides; (C) from about 1 wt % to about 60 wt % of a polyamide component comprising one or more polyamides having a melting peak temperature of at least 160° C.; and, optionally (D) one or more additional components selected from the group consisting of fillers, plasticizers, waxes, pigments, and colorants; wherein said blend composition has a Mooney viscosity (ML 1+4, 100° C.) determined according to ASTM D1646 of 5 to 200; wherein said blend composition, upon curing, forms a thermoset material; and wherein each of the weight percentages of the ethylene vinyl acetate copolymer, polyacrylate elastomer, and polyamide components are based on the combined weight of the ethylene vinyl acetate copolymers, polyacrylate elastomers, and polyamides in the blend composition.
