| 摘要 |
The present invention relates to a metallocene compound containing at least two metallocene fragments L-MX2-L which are different from one another and having the formula I (I) where B is a bridging unit, m is an integer from 2 to 100,000, M is a metal atom of group IVb, Vb or VIb of the Periodic Table of the Elements, X are identical or different in one metallocene fragment L-MX2-L and are each, independently of one another, hydrogen, a C1-C40-hydrocarbon-containing group, an OH group, a halogen atom or a pseudohalogen, L are identical or different in one metallocene fragment and are each, independently of one another, a n ligand or another electron donor. The metallocene compound can advantageously be used as a catalyst component for olefin polymerization.
