METHOD FOR PRODUCING BUTENE-ETHYLENE COPOLYMER

摘要

Disclosed is a method for producing a butene-ethylene copolymer, which comprises copolymerization of 1-butene and ethylene in the presence of an olefin polymerization catalyst which contains a transition metal complex represented by the formula (1) below as a catalyst component. The method for producing a butene-ethylene copolymer is characterized by obtaining a butene-ethylene copolymer having an 1-butene content of not less than 60 mol%, an Mw of not less than 200,000 and an Mw/Mn of not more than 3. formula (1) (In the formula, M, A, B, Flu, X1, X2 and R1-R6 are as defined in the description.) This method enables to obtain a high-molecular-weight ethylene-butene having high 1-butene content.
