ABSTRACT:
Desirable thermoplastic vulcanizates can be prepared from a polar engineering thermoplastic; a halogenated copolymer of p-alkylstyrene and an isomonoolefin having from 4 to 7 carbon atoms; and either an ethylene rubbery polymer or a diene based rubbery polymer or combinations thereof. The ethylene rubbery polymer desirably has at least one pendant carboxylic acid group, amine group, epoxy group, hydroxyl group or an anhydride of two carboxylic acid groups or combinations thereof. Desirable diene based rubbery polymers include epoxidized natural rubber and epoxidized homopolymers and copolymers of dienes.
