The present disclosure relates to a catalyst component for the polymerization of olefins comprising Mg. Ti and an electron donor such as mercaptoester derivatives of the general formula (I).
in which Z is selected from C, Si, O, N, S or P, with the proviso that the atoms O, S, P and N are not directly linked to either the carboxylic group or the sulfur atom of formula (I), the R2 groups, equal to or different from each other, are selected from hydrogen or a C1-C20 hydrocarbon radicals, optionally containing a heteroatom selected from halogen, P, S, N, O and Si, which can be fused together to form one or more cycles, m is a number satisfying the valences of Z and n is an integer ranging from 1 to 10, X is O or S, Y is —OR3, —NR4R5) or R6 groups in which R1 and R3 are selected from C1-C15 hydrocarbon groups, optionally containing a heteroatom selected from halogen, P, S, N, O, and Si, R4-R5 groups, independently, are hydrogen or R1 groups, and R6 groups have the same composition as R1 groups.
本公开涉及一种用于烯烃聚合的催化剂组分,由 Mg.Ti和电子供体,如通式(I)的巯基酯衍生物。
其中 Z 选自 C、Si、O、N、S 或 P,但 O、S、P 和 N 原子不与式 (I) 的羧基或硫原子直接相连,R2 基团彼此相等或不同,选自氢或 C1-C20 烃基,任选含有选自卤素、P、S、N、O 和 Si 的杂原子,可融合在一起形成一个或多个循环、m是满足Z的价数,n是1至10的整数,X是O或S,Y是-OR3、-NR4R5)或R6基团,其中R1和R3选自C1-C15烃基,任选含有选自卤素、P、S、N、O和Si的杂原子,R4-R5基团独立地为氢或R1基团,R6基团的组成与R1基团相同。
