Title:
担持メタロセン触媒、その製造方法及びそれを利用したポリオレフィンの製造方法
Document Type and Number:
Japanese Patent JP4652343
Kind Code:
B2
Abstract:
Provided are a supported metallocene catalyst which has excellent supporting efficiency due to an interaction between a cocatalyst supported on a carrier and a metallocene compound substituted with a functional group that can function as a Lewis base, such as acetal, ketal, tert-alkoxy alkyl, benzyloxy alkyl, substituted benzyloxy alkyl, monothioacetal, or monothioketal, and a method of polymerizing an olefin using the supported metallocene catalyst. In the supported metallocene catalyst, the metallocene catalyst is strongly bound to the carrier due to a Lewis acid-base interaction between the metallocene compound and the cocatalyst, and thus the metallocene catalyst is not separated from the carrier during the polymerization of polyolefin in a slurry or gas phase method. Thus, fouling is prevented and the prepared polymer has a good particle shape and a high apparent density. Thus, the supported metallocene catalyst can be suitably used in a conventional slurry or gas phase polymerization process.
