    Abstract: Supported catalyst systems are obtained by reacting support materials with organic compounds of alkali, alkaline earth or Main Group III or IV metals in an inert solvent and then reacting the suspension with a metallocene complex and a metallocenium ion-forming compound without removing solvent or isolating the first-stage product. A process for the production of a supported catalyst system comprises (1) reacting an organic or inorganic support material in an inert solvent with a metal compound of formula (I): M (R )r(R )5(R )t(R )u (I) in which: M = an alkali metal, alkaline earth metal or a Main Group III or IV metal; R = H, 1-10C alkyl, 6-15C aryl, or alkyl-aryl or aralkyl with 1-10C alkyl and 6-20C aryl groups; R -R = H, halogen, 1-10C alkyl, 6-15C aryl, or alkyl-aryl, aralkyl, alkoxy, aryloxy or dialkylamino (all with 1-10C alkyl and/or 6-20C aryl groups); r = 1-4; s, t, u = 0-3; (r+s+t+u) = the valency of M and then (2) reacting the suspension obtained with a metallocene complex and a metallocenium ion-forming compound, without removing the solvent and without isolating the pretreated support material from stage (1).

    Abstract: A process is disclosed for preparing ethylene polymers with a molecular weight Mw (weight average) lower than 20,000 g/mole at temperatures in a range from 200 to 280 DEG C and pressures in a range from 1000 to 3500 bars in the presence of a catalyst system. The catalyst system used contains: (A) a non-bridged substituted or unsubstituted biscyclopentadienyl complex; (B) a metal compound of general formula (I) M (R )r (R )s (R )t, in which M is an alkaline, an alkaline earth metal or a metal of the third main group of the periodic table; R is hydrogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl or arylalkyl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R and R independently represent hydrogen, halogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl, arylalkyl or alkoxy with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; r is an integer from 1 to 3; and s and t are integers from 0 to 2, the sum r+s+t corresponding to the valency of M ; and (C) a metallocene ion-forming compound selected in a group which consists of strong, neutral Lewis acids, ionic compounds with lewis acid cations and ionic compounds with Brönsted acids as cations. Components (A), (B) and (C) are mixed together and after at the latest 5 minutes are dosed in the reactor.
