摘要：
A supported catalyst system that is obtained bya) 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; andd) optionally adding an open-chain or cyclic alumoxane compound.The catalyst system can be used to prepare polymers of C.sub.2 -C.sub.10 -alk-1-enes.
