Abstract
Thermoplastic vulcanizates from semicrystalline polyolefins and blends of crosslinked rubbers are disclosed. The blends are a mixture of at least two rubbers. One rubber is a copolymer predominantly of C.sub.4 to C.sub.7 isomonoolefins (e.g. isobutylene), along with optional monomers of conjugated dienes and/or p-alkylstyrene. This copolymer is optionally halogenated. The second rubber is ethylene/propylene rubber, natural rubber or a rubber polymerized predominantly from a conjugated diene. Such rubbers include polybutadiene, nitrile rubber, butadiene-styrene copolymers or combinations thereof.
