Abstract

In a process for preparing a supported catalyst which comprises the following steps:A) reacting an inorganic support material with an organometallic compound IB) reacting the support material obtained as described in A) with a metallocene complex and a compound capable of forming metallocenium ions andC) subsequently reacting the resulting material with an organometallic compound II,the supported catalyst obtained in this way or its precursor is brought into contact with a Lewis base in an amount of from 0.1 to <10 mole per mole of metallocene complex.
