ABSTRACT:
A supported catalyst for olefin polymerization comprisesA) as support material, a copolymer comprising the monomer units I, II and III,where the monomer units I have the formula (I) and the monomer units II have the formula (II), where the variables have the following meanings:R1is hydrogen, C1-C4-alkyl or phenyl,R2is substituted or unsubstituted aryl or branched or unbranched alkyl or alkenyl,A1is a direct chemical bond or a substituted or unsubstituted phenylene group,R3are identical or different and are each hydrogen, C1-C10-alkyl or substituted or unsubstituted phenyl,p is an integer from 0 to 8, andR4to R7are hydrogen, C1-C10-alkyl or substituted or unsubstituted phenyl,and the monomer units III have polar groups, andB) at least one metallocene complex andC) at least one compound capable of forming metallocenium ions.A process for preparing such supported catalysts, copolymers suitable as support material and a process for the polymerization of olefins in the presence of a catalyst according to the present invention are also provided.
