Catalyst for olefin polymerization, process for olefin polymerization using the same, ethylene/ alpha -olefin copolymer, graft modified ethylene/ alpha -olefin copolymer, and ethylene copolymer composition

摘要

An ethylene/ alpha -olefin copolymer obtained by copolymerizing ethylene with an alpha -olefin of 3 to 20 carbon atoms in the presence of a catalyst for olefin polymerization comprising an organoaluminum oxy-compound (a) and at least two kinds of transition metal compounds (b). This ethylene/ alpha -olefin copolymer has high melt tension and high flowability.
