Metallocene (co)polymers, process for their preparation and their use as catalysts

Claim 1

A polymerized, immobile, metallocene catalyst component comprising a metallocene which has been polymerized or co-polymerized or a metallocene co-polymerized with a vinyl-aromatic or divinyl-aromatic compound, said metallocene being one or both of the compounds of formulas I and II ##STR8## and/or of formula II ##STR9## in which M 1 is zirconium or hafnium and Cp is a cyclopentadienyl radical, R 1 and R 2 are identical or different and are a hydrogen atom, a halogen atom, a C 1 -C 10 -alkyl group, a C 1 -C 10 -alkoxy group, a C 7 -C 20 -arylalkyl group, a C 6 -C 10 -aryl group or a C 6 -C 10 -aryloxy group, and R 1 and R 2 can also be linked to one another and together with M 1 can form a metallo ring, the radicals R 3 are identical or different and are a hydrogen atom, a halogen atom, a C 1 -C 10 -alkyl group, a C 6 -C 10 -aryl group, a C 7 -C 20 -arylalkyl group, a C 1 -C 10 -fluoroalkyl group or an organometallic radical, such as C 1 -C 10 -trialkylsilyl, C 6 -C 10 -aryl-C 1 -C 10 -dialkylsilyl, C 1 -C 10 -alkyl-C 6 -C 10 -diarylsilyl or C 6 -C 10 -triarylsilyl, R 4 and R 5 are identical or different and are a vinyl group, a C 6 -C 18 -arylvinyl group, a C 1 -C 8 -alkylvinyl group or a C 6 -C 18 -vinylaryl group, all of which may be substituted, R 6 and R 7 are identical or different and are a cyclopentadienyl, indenyl or fluorrenyl radical, it being possible for said rings together with M 1 to form a sandwich structure, R 8 and R 9 are identical or different, are substitutents of R 6 and R 7 and have the meanings given for R 3 , R 4 and R 5 , with the proviso that R 6 and R 7 can be monosubstituted or polysubstituted by R 8 or R 9 , but at least one ring R 6 or R 7 must carry at least one radical R 8 or R 9 having the meaning of R 4 and R 5 , and R 10 has the meaning shown in formulae III-VII ##STR10## where M 2 is silicon, germanium or tin and R 11 , R 12 , R 13 and R 14 are identical or different and are a hydrogen atom, a halogen atom, a C 1 -C 10 -alkyl group, a C 1 -C 10 -fluoroalkyl group, a C 6 -C 10 -aryl group, a C 6 -C 10 -fluoroaryl group, a C 1 -C 10 -alkoxy group, a C 6 -C 10 -aryloxy group or a C 7 -C 20 -arylalkyl group, R 11 and R 12 , R 13 and R 14 , R 11 and R 13 or R 12 and R 14 together with the atoms linking them can form a ring system and m and n are identical or different and are a number from 0 to 5, where m+n must be ≧1.
