摘要： The present invention provides a process for producing an α-olefin polymer comprising polymerizing or copolymerizing (a) C 3 or higher α-olefin(s) in the presence of an olefin polymerization catalyst comprising solid titanium catalyst component (I) containing titanium, magnesium, halogen, and a compound with a specific structure having two or more ether linkages and organometallic catalyst component (II) with high catalytic activity. In this process, particularly even in (co)polymerizing (a) higher olefin(s), demineralization is unnecessary. A 4-methyl-1-pentene-based polymer obtained by polymerization using the catalyst of the present invention is excellent in tacticity, transparency, heat resistance, and releasability, and the polymer is particularly suitable for a release film.

摘要： This invention relates to a process for producing an α-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 α-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.
