Document Type and Number:
WIPO Patent Application WO/2019/003852
Kind Code:
A1
Abstract:
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 onganoaluminum 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.
