A metallocene procatalyst compound comprising a group 3 to 7 transition metal and a multisiloxy substituted cyclopentadienyl ligand or a multisiloxy substituted bicyclic cyclopentadienyl ligand with the proviso that if a siloxy group is present in the 6 membered ring of an indenyl ligand, then at least two siloxy substituents must be present on adjacent carbon atoms forming the bicyclic ring.
一种包括3到7族过渡金属和多硅氧基取代的环戊二烯基配体或多硅氧基取代的双环环戊二烯基配体的金属环烯烃催化剂化合物,但如果在吲哚基配体的6元环中存在硅氧基,则必须至少在形成双环环的相邻碳原子上存在两个硅氧基取代基。
