ETHYLENE COPOLYMER RUBBER, VULCANIZABLE RUBBER COMPOSITION CONTAINING THE COPOLYMER RUBBER, AND PROCESS FOR PREPARING THE COPOLYMER RUBBER |
摘要 |
Disclosed is an ethylene copolymer rubber which is a random copolymer rubber of (a) ethylene, (b) an .alpha.-olefin of 3 to 20 carbon atoms, (c) a nonconjugated polyene containing, in one molecule, one carbon-to-carbon double bond polymerizable by a metallocene catalyst among carbonto-carbon double bonds, and (d) a nonconjugated polyene containing, in one molecule, two carbon-to-carbon double bonds polymerizable by the metallocene catalyst among carbon-to-carbon double bonds. The ethylene copolymer rubber has excellent moldability, high vulcanization rate, good mechanical properties such as high vulcanization strength, excellent low-temperature flexibility and thermal aging resistance. Also disclosed is a process for preparing the ethylene copolymer rubber with high activity, high conversion ratio of .alpha.-olefin and high random copolymerizability.
