Abstract:
A thermoplastic elastomer vulcanizate comprising(a) about 15 to about 70% by weight of at least one thermoplastic torpolymer consisting essentially of about 2 to about 15% by weight of ethylene monomeric units, about 80 to about 96% by weight of propylene monomeric units, and about 15 to about 2% by weight of &agr;-olefin monomeric units containing 4 to 8 carbon atoms, wherein the weight percent of said monomeric units is based on the total weight of said terpolymer, and (b) about 85 to about 30% by weight of at least one rubber component which has been fully cured with a non-peroxide curing system, such that no more than about 4% by weight of the curable rubber is extractable in cyclohexane at 23Â° C., wherein the weight percent of said terpolymer and said rubber is based on the total weight of (a)+(b).
