摘要
Disclosed is an olefin polymer-based thermoplastic elastomer comprising a propylene polymer material, an amorphous olefin copolymer rubber, and optionally a semicrystalline, essentially linear ethylene-C3-4 alpha-olefin copolymer, having incorporated therein zinc salts of certain mercapto compounds and sterically hindered di-tertiary butyl phenol compounds. The compositions exhibit good retention of properties at elevated temperatures.
