The present invention relates to a solid catalyst component for the polymerization of olefins CH
2
═CHR in which R is hydrogen or a hydrocarbon radical with 1-12 carbon atoms, comprising Mg, Ti, halogen and an electron donor selected from substituted succinates of a particular formula. Said catalyst components when used in the polymerization of olefins, and in particular of propylene, are capable to give polymers in high yields and with high isotactic index expressed in terms of high xylene insolubility.
本发明涉及一种用于烯烃聚合的固体催化剂组分 CH
2
═CHR,其中 R 为氢或含有 1-12 个碳原子的烃基,由 Mg、Ti、卤素和选自特定式的取代琥珀酸盐的电子供体组成。上述催化剂组分用于烯烃,特别是丙烯的聚合时,能够产生高产率和高同素异形指数的聚合物,以高二甲苯不溶性表示。
