A catalyst for olefin polymerization comprising the following Components (A) to (D), Component (D) being optional, in combination:
(A): a solid catalyst component comprising Ti, Mg, a halogen and an electron donor;
(B): an organoaluminum compound;
(C): a sulfonic ester represented by R4SO3R5 (R4 and R5: hydrocarbon group); and
(D): an organosilicon compound.
The electron-donating compound comprised in Component (A) is specified in one aspect of the invention.
Olefin polymers having excellent moldability and processability and extremely high crystallinity can be produced in high yield when the above catalyst is used.
一种用于烯烃聚合的催化剂,由以下组分(A)至(D)组合而成,组分(D)是可选的:
(A): 由 Ti、Mg、卤素和电子供体组成的固体催化剂组分;
(B) 有机铝化合物
(C) 由 R4SO3R5 表示的磺酸酯(R4 和 R5:烃基);以及
(D) 有机硅化合物。
组分(A)中包含的电子供体化合物在本发明的一个方面中进行了具体说明。
当使用上述催化剂时,可以高产率生产出具有优异成型性和加工性以及极高结晶度的烯 烃聚合物。
