Abstract

Supported catalyst systems are obtainable byA) reaction of an inorganic carrier with a metal compound of the general formula IM1(R1)r(R2)s(R3)t(R4)u  I whereM1 is an alkali metal, an alkaline earth metal or a metal of main group III or IV of the Periodic Table,R1 is hydrogen, Ch1-C10-alkyl, C6-C15-aryl, alkylaryl or arylalkyl each having 1 to 10 carbon atoms in the alkyl radical and 6 to 20 carbon atoms in the aryl radical,R2 to R4 are each hydrogen, halogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl, arylalkyl, alkoxy or dialkylamino each having 1 to 10 carbon atoms in the alkyl radical and 6 to 20 carbon atoms in the aryl radical,r is an integer from 1 to 4 ands, t and u are integers from 0 to 3 the sum r+s+t+u corresponding to the valency of M1,B) reaction of the material obtained according to A) with a metallocene complex in its metal dihalide form and a compound forming metallocenium ions andC) subsequent reaction with a metal compound of the general formula IIM2(R5)o(R6)p(R7)q  II whereM2 is an alkali metal, an alkaline earth metal or a metal of main group III of the Periodic Table,R5 is hydrogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl or arylalky…
