The present invention relates to new bis(metallocene) compounds, new catalyst compositions, process for preparing the new bis(metallocene) compounds and use of said new catalyst compositions to polymerise olefins. The bis(metallocene) compounds of the invention are homo- or hetero bis(metallocene) molecules in which same or different metallocene moieties are connected by a phenylene bridge. The phenylene bridge is either para-substituted, meta-substituted or ortho-substituted by the two metallocene moieties.
本发明涉及新的双(
金属茂)化合物、新的催化剂组合物、制备新的双(
金属茂)化合物的方法以及使用所述新的催化剂组合物聚合烯烃的方法。本发明的双(
金属茂)化合物是同种或异种双(
金属茂)分子,其中相同或不同的
金属茂基团通过苯基桥连接。苯基桥由两个
金属茂基团的对位、间位或邻位取代。
