摘要:
A catalyst component for olefin polymerization comprising an α-cyanosuccinate compound as an internal electron donor, a catalyst comprising the catalyst component, and use of the catalyst in olefin polymerization. When used in propylene polymerization, the catalyst can exhibit good catalytic activity and good hydrogen response, and the resulting polymer can have a good isotacticity and a good molecular weight distribution.
