Abstract:
A process for the preparation of a 1-olefin polymer by polymerizing a 1-olefin of the formula R--CH.dbd.CH.sub.2 in which R is an alkyl group having 1 to 28 carbon atoms or copolymerizing these olefins together with ethylene at a temperature from -60.degree. to 200.degree. C., under a pressure of 0.5 to 60 bar, in solution, in suspension or in the gas phase and in the presence of a catalyst system comprising the reaction product obtained by dissolving a metallocene in a solution of an aluminoxane in an inert hydrocarbon wherein the aluminoxane is present in a concentration from approximately 1% by weight to the saturation limit.
