Cyclopolyenic 1,3-diethers wherein the carbon atom in position 2 belongs to a particular cyclic or polycyclic structure containing two or three unsaturations, solid catalyst components and catalysts therefrom, the catalysts comprising the reaction product of:
i. a solid catalyst component containing an internal donor;
ii. an Al-alkyl compound, and optionally
iii. an external donor; the internal donor and/or the external donor being cyclopolyenic 1,3-diethers. The catalysts are useful for the polymerization of alpha-olefins.
环多烯 1,3-二醚,其中位于第 2 位的碳原子属于特定的环状或多环状结构,包含两个或三个不饱和结构,固体催化剂组分及其催化剂,催化剂包括以下物质的反应产物:
i. 含有内部供体的固体催化剂组分;
铝烷基化合物,以及可选的
iii. 外部供体;内部供体和/或外部供体为环多烯 1,3-二醚。这些催化剂可用于α-烯烃的聚合。
