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.
