A solid catalyst component which exhibits high activity and stereospecificity in the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I)
where R and R1 are selected from the group consisting of C1-C20 hydrocarbon groups, C6-C14 aryl or alkylaryl groups hydrocarbon groups, optionally containing a heteroatom selected from the group consisting of halogens, P, S, N, and O; R2 to R11 groups, equal to or different from each other, are hydrogen, halogen or C1-C15 hydrocarbon groups which can be optionally fused together to form one or more cycles with the proviso that R6 and R11 cannot join together to form a phenyl ring.
一种固体催化剂组分,在由 Mg、Ti 和式 (I) 电子供体制成或含有这些物质的烯烃聚合过程中具有高活性和立体特异性
其中 R 和 R1 选自 C1-C20 烃基、C6-C14 芳基或烷基芳基烃基组成的组,可选择含有一个选自卤素、P、S、N 和 O 组成的组的杂原子;R2 至 R11 基团彼此相同或不同,均为氢、卤素或 C1-C15 烃基,可选择融合在一起形成一个或多个循环,但 R6 和 R11 不能连接在一起形成苯环。
