The present invention discloses a Ziegler-Natta catalyst system for olefin polymerization, comprising at least one compound represented by formula (I) as (i) an internal electron donor, (ii) an external electron donor, or (iii) the both, wherein M1, M2, M3, M4, M5, M6, M1′, M2′, M3′, M4′, M5′ and M6′ are each independently selected from the group consisting of hydrogen, hydroxy, amino, aldehyde group, carboxy, acyl, halogen atoms, —R1 and —OR2, wherein R1 and R2 are each independently a C1-C10 hydrocarbyl, which is unsubstituted or substituted by a substituent selected from the group consisting of hydroxy, amino, aldehyde group, carboxy, acyl, halogen atoms, C1-C10 alkoxy and heteroatoms; and wherein, when among M1-M6 and M1′-M6′, any two adjacent groups on the same phenyl ring are each independently selected from the group consisting of R1 and —OR2, the two adjacent groups may optionally be linked to form a ring, with a proviso that M1, M2, M3, M4, M5, M6, M1′, M2′, M3′, M4′, M5′ and M6′ are not simultaneously hydrogen.
本发明公开了一种用于烯烃聚合的齐格勒-纳塔催化剂体系,它包括至少一种由式(I)代表的化合物作为(i)内部电子供体、(ii)外部电子供体,或(iii)两者,其中 M1、M2、M3、
M4、M5、M6、M1′、M2′、M3′、
M4′、M5′和 M6′各自独立地选自氢组成的组、羟基、
氨基、醛基、羧基、酰基、卤素原子、-R1 和 -OR2,其中 R1 和 R2 各自独立地为 C1-C10 碳氢基,该碳氢基未被取代或被选自羟基、
氨基、醛基、羧基、酰基、卤素原子、C1-C10 烷氧基和杂原子的取代基取代;其中,当在 M1-M6 和 M1′-M6′ 之间时,同一苯环上的任何两个相邻基团各自独立地选 自由 R1 和 -OR2 组成的组、这两个相邻基团可任选连接形成一个环,但 M1、M2、M3、
M4、M5、M6、M1′、M2′、M3′、
M4′、M5′和 M6′不能同时为氢。
