doi:10.11949/j.issn.0438-1157.20180688

Abstract

Abstract:

Ethylene-propylene rubber is widely used in automotive parts, wire and cable, building materials, heat-resistant hoses, sealing components and other related fields due to its excellent structure, saturated main chain and good aging resistance. The catalyst and polymerization process are absolutely essential to ethylene-propylene copolymerization. In this paper, the polymerization feature of EP(D) M catalyzed by Ziegler-Natta catalyst, metallocene catalyst, supported metallocene catalyst and non-metallocene catalyst was presented. The polymerization process of solution polymerization, suspension polymerization and gas polymerization and some new species of EP(D) M was also introduced. Finally, the future development trend of EP(D) M is prospected.

Key words: EP(D) M, catalyst system, polymerization process
