Title:
エチレン／α−オレフィン共重合体の製造方法
Document Type and Number:
Japanese Patent JP6492018
Kind Code:
B2
Abstract:
A process capable of producing an ethylene/±-olefin copolymer having a high molecular weight even under the conditions of a high polymerization temperature is provided. The process for producing an ethylene/±-olefin copolymer includes copolymerizing ethylene and an ±-olefin having 3 or more carbon atoms in the presence of an olefin polymerization catalyst including a crosslinked metallocene compound (A) represented by the following general formula [I] and a cocatalyst component (B). In the general formula [I], Y is selected from a carbon atom, etc. , M is a hafnium atom or the like, R 1 to R 12 are each selected from a hydrogen atom, a hydrocarbon group, etc., R 13 and R 14 are each a substituted aryl group or the like, at least one of R 13 and R 14 is a substituted aryl group having one or more electron-donating substituents having a Hammett substituent constant à of not more than -0.2, Q is selected from a halogen atom, etc., and j is an integer of 1 to 4.
