The present invention relates to a solid 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 exhibits a higher catalytic activity and good hydrogen response, and the resulting polymer has a high isotacticity and a broad molecular weight distribution.
本发明涉及一种用于烯烃聚合的固体催化剂组分,该组分包括一种作为内部电子供体的α-氰基琥珀酸酯化合物、一种由该催化剂组分组成的催化剂以及该催化剂在烯烃聚合中的用途。当用于丙烯聚合时,催化剂表现出更高的催化活性和良好的氢响应,所产生的聚合物具有高同构度和宽分子量分布。
