Metallocene Catalyzed Ethylene/Alpha Olefin Copolymers Used in Thermoplastic Elastomers

Abstract Thermoplastic elastomers (TPEs) continue to be a focus of significant research as well as commercial development in the rubber industry since their origin over forty years ago. A wide variety of TPEs exist today. Ethylene copolymer and terpolymer based elastomers continue to play an increasing role in this arena. New ethylene copolymers and terpolymers, based upon metallocene catalysis, have further diversified the TPE portfolio. Compounders are now using these new elastomers as modifiers for existing TPEs as well as the principle elastomer in new TPEs
