Supported metallocene complexes having heterofunctional groups in the cyclopentadienyl system as catalyst systems

摘要

A supported catalyst system that is obtained by a) reacting a finely divided carrier with an a-trisalkoxy-silyl- omega -haloalkyl compound, b) adding a metallocene complex of the indicated formula I to the reaction product of a); c) reacting the product of b) with a quaternizing agent; and d) optionally adding an open-chain or cyclic alumoxane compound. The catalyst system can be used to prepare polymers of C2-C10-alk-1-enes.
