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 .

Abstract: A process for the preparation of polymers of C2- to C10-alk-1-enes at pressures of from 0.5 to 3000 bar and temperatures of from -50 to 300 DEG C using a catalyst system, characterised in that the catalyst systems used are those containing, as active constituents, a) metallocene complexes of the formula I b) an open-chain or cyclic aluminoxane compound. lk

Abstract: A process is disclosed for producing propene/but-1-ene copolymers in which the molar ratio between propene and but-1-ene lies in a range from 10,000:1 to 4:1. Polymerisation is continuously carried out at temperatures in a range from 50 to 120 DEG C. Systems that contain as active components (A) metallocene complexes; (B) a metallocene ion-generating compound; and optionally (C) an aluminium compound, are used as catalyst systems.

Abstract: The invention concerns a process for converting the achiral meso form or the racemate of an ansa-metallocene complex or mixtures thereof into one of its enantiomers. The conversion is carried out photochemically in the presence of an enantiomerically pure auxiliary reagent.
