Ethylene/alpha-olefin copolymer |
摘要 |
<p>An olefin polymerization catalyst comprising an organoaluminium oxy-compound (a) and two cyclopentadienyl transition metal compounds (b-I) and (b-II). A process for olefin polymerization in the presence of the catalyst and ethylene/ alpha -olefin copolymer obtainable by copolymerizing ethylene with an alpha -olefin in the presence of the catalyst. <??>Graft modified ethylene/ alpha -olefin copolymer obtainable by graft polymerizing the above-mentioned ethylene/ alpha -olefin copolymer with a polar monomer, and composition comprising the graft modified copolymer and polyolefin. <??>The ethylene/ alpha -olefin copolymer produced is excellent in moldability and has high melt tension and high flowability. A film having high transparency and high mechanical strength can be produced from it.</p> |
