    摘要： Random propylene thermoplastic copolymers can be used to increase the elongation to break and toughness of thermoplastic vulcanizates. Semi-crystalline polypropylene is a preferred thermoplastic phase. The rubber can be olefinic rubbers. Random thermoplastic polypropylene copolymers are different from conventional Ziegler-Natta propylene copolymers as the compositional heterogeneity of the copolymer is greater with Ziegler-Natta copolymers. This difference results in substantial differences in properties (elongation to break and toughness) between thermoplastic vulcanizates modified with random thermoplastic propylene copolymers and those modified with conventional Ziegler-Natta propylene copolymers. An increase in elongation to break results in greater extensibility in the articles made from a thermoplastic vulcanizate.

    摘要： 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.

    摘要： A thermoplastic vulcanizate (TPV) from a blend of a first thermoplastic polyolefin, a second thermoplastic olefin and a rubber is described. The rubber is crosslinked with a hydrosilylation crosslinking agent. The second polyolefin includes at least one OR group pendant to a Si atom chemically attached via one or more intermediate molecules to said second polyolefin. R can be hydrogen or an alkyl of 1 to 8 carbon atoms. The OR groups can react with the hydrosilylation catalyst to reduce the compression set of the TPV.
