A thermoplastic elastomer of EPDM/HPVC with excellent properties was prepared by dynamic vulcanization. The effects of the rubber/plastics ratio, the content of plasticizer and vulcanizing agent on the mechanical properties of EPDM/HPVC were investigated in detail. Results indicate when the mass ratio of EPDM/HPVC was 30/70, CPE was 9 phr, sulfur was 0.4 phr, EPDM/HPVC had an excellent mechanical property and aging resistance. EPDM/HPVC prepared by dynamic vulcanization had a typical sea-island two phase structure in which smaller EPDM particle dispersed uniformly in the continuous phase of HPVC.
