Abstract
Blends of crystalline EPDM rubbery polymers, high m.w. ethylene-vinyl acetate copolymers and polyalphamethyl styrene exhibit good processing characteristics and physical properties. Part of the EVA may be replaced with low m.w. crystalline polyethylene. The addition of reinforcing agents will raise the modulus and other physical properties while still retaining favorable processing characteristics.
