According to the invention a new catalyst precursor is obtained, in which alkoxy or siloxy substitution in the 2-position of 5-membered ring of indenyl compound has been carried out. Thereby a metallocene compound is achieved, in which an oxygen atom is directly bonded to the 2-position of a pentahapto indenyl moiety. The catalyst precursors can be used as components for olefin polymerization catalysts.
根据这项发明,获得了一种新的催化剂前体,其中对
茚基化合物的5元环的2位进行了烷氧基或
硅氧基取代。从而获得了一种
金属茂化合物,其中氧原子直接键合到五环
茚基的2位。这些催化剂前体可以用作烯烃聚合催化剂的组分。
