Title:
SOLID TITANIUM CATALYST COMPONENT, CATALYST FOR OLEFIN POLYMERIZATION, AND PROCESS FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2006/054613
Kind Code:
A1
Abstract:
This invention relates to a process for producing an &agr -olefin polymer that has high catalytic activity and can particularly realize a deliming-free process even in polymerization of a higher olefin. The production process comprises polymerizing or copolymerizing an &agr -olefin having 3 or more carbon atoms in the presence of a catalyst for olefin polymerization comprising a solid titanium catalyst component (I) comprising a titanium element, a magnesium element, and a halogen element and a compound containing two or more ether bonds having a specific structure, and an organometal compound catalyst component (II). A 4-methyl-1-pentene polymer produced by polymerization in the presence of the catalyst according to the present invention has excellent stereoregularity, transparency, heat resistance, and releasability and is particularly suitable as a release film.
