Disclosed is a catalyst component for olefin polymerization. The catalyst component comprises magnesium, titanium, halogen and an internal electron donor. The internal electron donor includes an imine compound with a ketone group as shown in Formula I. Disclosed further is a method of preparing the catalyst component, and a catalyst for olefin polymerization containing the catalyst component. When the catalyst is used in olefin polymerization reaction especially propene polymerization reaction, the catalyst has a high long-term activity and good hydrogen response, and the obtained polymer has characteristics of an adjustable isotactic index and a relatively wide molecular weight distribution.
公开了一种用于烯烃聚合的催化剂组分。催化剂组分包括镁、钛、卤素和内部电子供体。内部电子供体包括如式 I 所示的带有酮基的亚胺化合物。进一步公开的是制备催化剂组分的方法,以及含有该催化剂组分的烯烃聚合催化剂。当催化剂用于烯烃聚合反应,特别是丙烯聚合反应时,催化剂具有较高的长期活性和良好的氢响应,得到的聚合物具有可调节的同素异形指数和相对较宽的分子量分布。
