Thermoplastic elastomeric compositions

摘要

A thermoplastic elastomeric composition comprising a dynamically crosslinked grafted polyolefin copolymer elastomer and a thermoplastic crystalline polyolefin is disclosed. The crosslinked elastomer is dispersed in the thermoplastic crystalline polyolefin which is present as the continuous phase. The grafted elastomer is ethylene/propylene/diene terpolymer or ethylene/propylene copolymer grafted with fumaric acid, maleic acid, maleic anhydride or derivatives thereof capable of reacting with diamine crosslinking agents.
