THERMALLY PLASTIC ELASTOMER OF PROPYRENE POLYMER MATERIAL AND CROSS-LINKED ETHYLENE- PROPYRENE RUBBER

摘要

Disclosed is a dynamically partially cured thermoplastic elastomer comprising a propylene polymer material, an amorphous ethylene-propylene copolymer rubber, a semi-crystalline, low density, essentially linear ethylene-propylene copolymer and a curing system containing 1,2-polybutadiene and an organic peroxide and a method of making the same.
