    Abstract: A process for producing polymers of alkenes by suspension polymerisation in the presence of catalyst systems where use is made of supported catalyst systems obtainable by A) reacting an inorganic support material with a metal compound of the general formula (I): M (R )r(R )s(R )t(R )u, in which M is an alkaline or alkaline earth metal or a metal from main group III or IV of the periodic system; R is hydrogen, C1-C10 alkyl, C6-C15 aryl, alkyl aryl or aryl alkyl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R to R are hydrogen, C1-C10 alkyl, C6-C15 aryl, alkyl aryl or aryl alkyl, alkoxy or dialkylamino with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; r is a whole number from 1 to 4; and s, t and u are whole numbers from 0 to 3, where the sum r+s+t+u corresponds to the valency of M ; B) reacting the material obtained from A) with a metallocene complex in its metal dihalogenide form and a metallocenium ion-forming compound; and C) subsequent reaction with a metal compound of the general formula (II): M (R )o(R )p(R )q, in which M is an alkaline or alkaline earth metal or a metal of main group III of the periodic system; R is hydrogen, C1-C10 alkyl, C6-C15 aryl, alkyl aryl or aryl alkyl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R and R are hydrogen, halogen, C1-C10 alkyl, C6-C15 aryl, alkyl aryl, aryl alkyl, or alkoxy with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical, o is a whole number from 1 to 3; and p and q are whole numbers from 0 to 2 where the sum o+p+q corresponds to the valency of M .
