用于烯烃聚合的催化剂组分
摘要：
用于烯烃聚合的催化剂组分，其包括Mg、Ti以及属于特定式(Ⅰ)的巯基酯衍生物的电子给体，其中，Z选自C、Si、O、N、S或者P，条件是原子O、S、P和N未直接链接至式(Ⅰ)的羧基基团或者硫原子，彼此相等或者不同的R2基团是氢或者C1‑C20烃基，可选地包含选自卤素、P、S、N、O和Si的杂原子，其可以被熔合在一起以形成一个或多个环，m是满足Z的化合价的数字，并且n是从1至10的整数，X是O或者S，Y是‑OR3、‑NR4R5)或者R6基团，其中，R1和R3选自C1‑C15烃基团，可选地包含选自卤素、P、S、N、O和Si的杂原子，R4‑R5基团独立地是氢，或者R1基团和R6基团具有与R1基团相同的意义。
摘要（英）：

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.
