| abstract |
The present invention relates to a polynuclear metallocene compound of the formula I <IMAGE> in which M <1> is a tetravalent metal, L <1> independently of one another are identical or different and are a substituted cyclopentadienyl group, L <2> and L <3> independently of one another or are a π ligand, B are independently the same or different each are a divalent bridging unit, X are independently the same or different and represent a hydrogen atom, a halogen atom, a C1-C10 fluorocarbon radical or a hydrocarbon-containing radical at 1-40 ° C -Atoms stand, and k is an integer from 0 to 10. The metallocene compound according to the invention is suitable as a catalyst component for the production of olefin polymers. |
