TH23929B - Ethylene copolymer rubber, a vulcanized rubber compound containing that copolymer rubber, and the rubber copolymer preparation process. - Google Patents

Abstract

The disclosed is ethylene copolymer rubber, which is the random copolymer of (a) ethylene (b) alpha-olefin of 3 to 20. Carbon atom (C) is conjugated polyene with one double bond. Carbon to carbon in one molecule that can be polymerized. By Metalosene Catlist during Bond Couple Carbon-to-carbon and (d) non-conjugated polyene with 2-bond carbon-to-carbon pairs. In one molecule That can be polymerized By metalocene catalyst during the carbon-to-carbon double bond, ethylene copolymer rubber has the In an excellent casting High vulcanization rate Good mechanical properties such as strength, high vulcanization Excellent low temperature softness And resistance to thermal aging. The process of ethylene copolymer with high activity, high alpha-olfin transition ratio, was also revealed. And high random copolymerization capability
