A solid catalyst component for olefin polymerization comprising titanium, magnesium and a compound of the general formula (I)
wherein R1 and R2 are independently a C3 straight or branched hydrocarbon group, R3 is hydrogen or a C1-4 straight hydrocarbon group, R4 is a C1-4 straight or branched hydrocarbon group or a C3-4 aliphatic cyclic hydrocarbon group when R3 is hydrogen, R4 is the same C1-4 straight hydrocarbon group as R3 when R3 is a C1-4 straight hydrocarbon group, and n is an integer of 1 to 10. A catalyst for olefin polymerization, containing this catalyst component, obtains a high activity with high stereospecificity.
一种用于烯烃聚合的固体催化剂组分,包括钛、镁和通式(I)的化合物
其中 R1 和 R2 独立地为 C3 直链或支链烃基,R3 为氢或 C1-4 直链烃基,当 R3 为氢时,R4 为 C1-4 直链或支链烃基或 C3-4 脂肪环烃基,当 R3 为 C1-4 直链烃基时,R4 为与 R3 相同的 C1-4 直链烃基,n 为 1-10 的整数。含有这种催化剂组分的烯烃聚合催化剂具有高活性和高立体特异性。
