Abstract:
A solid component of a supported catalyst system obtained by a process consisting essentially of the reaction of an inorganic support with a metallocene complex and a compound forming metallocenium ions, whereinA) the support is prepared by reaction of an inorganic carrier with a metal compound of the formula I M1(R1)r(R2)s(R3)t(R4)uâ€ƒâ€ƒI â€ƒwhere M1 is an alkali metal, an alkaline earth metal or a metal of main group III or IV of the Periodic Table, R1 is hydrogen, C1-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 and s, t and u are integers from 0 to 3, the sum r+s+t+u corresponding to the valency of M1, and subsequent removal of excess metal compound of the formula I and B) the material obtained according to A) is reacted with a metallocene complex in its metal dihalide form and a compound forming metallocenium ions selected from the group consisting of strong, neutral Lewis acids, ionic compounds having Lewis acid cations and ionic compounds having BrÃ¶nsted acids as cations.
