Thermoplastic vulcanizates from a cyclic olefin rubber, a polyolefin, and a compatiblizer

摘要

A blend of a semicrystalline polyolefin, a rubbery polymer containing repeat units from norbornene, and a polymeric compatibilizer is disclosed. This composition has reduced oil swell as compared to thermoplastic vulcanizates from a semicrystalline polyolefin and hydrocarbon rubbers.
