Title:
METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
Japanese Patent JP2002037810
Kind Code:
A
Abstract:

To obtain an ethylene/α-olefin copolymer which has an excellent polymerizability and a high molecular weight even at a high polymerization temperature of 120°C or more.

The copolymerization of ethylene and α-olefin of 3-20C is carried out at the polymerization temperature of 120°C or more, using an olefin polymerization catalyst which comprises (a) a metallocene compound, (b) a compound which cationizes the metallocene compound and forms a counteranion, (c) an organic aluminum compound and (d) a cray mineral.
