Process for producing ethylene/alpha-olefin copolymer.

摘要

A process for producing an ethylene/ alpha -olefin copolymer is provided in which ethylene is copolymerized with an alpha -olefin having three or more carbons by use of an olefin polymerization catalyst at a polymerization temperature of not lower than 120 DEG C. The olefin polymerization catalyst comprises, as constitutional components, a) a metallocene compound, b) an ionizing ionic compound, and c) an organoaluminum compound, the ionizing ionic compound (b) being a compound which is capable of changing the metallocene compound (a) into a cationic form and does not further react with the cationic form of the metallocene compound.
