Abstract
Official abstract text for this publication.
A solid catalyst component for olefin polymerization, an olefin polymerization catalyst, and a method for producing an olefin polymer, are disclosed. A solid catalyst component for olefin polymerization includes magnesium, a halogen, titanium, vanadium, and an internal electron donor compound selected by organic acid diester. An olefin polymerization catalyst includes the disclosed solid catalyst component for olefin polymerization, an organoaluminum promoter, and an optional external electron donor A method for producing an olefin copolymer includes copolymerizing ethylene and propylene using the disclosed olefin polymerization catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a solid catalyst component for olefin polymerization comprising bringing a vanadium compound into contact with a solid component that comprises magnesium, a halogen, titanium, and an internal electron donor compound. 2. The method for producing a solid catalyst component for olefin polymerization according to claim 1 , wherein the vanadium compound is brought into contact with the solid component in a molar ratio of 0.01 to 10 with respect to titanium.
