Abstract
A catalyst composition suitable for the (co)polymerization of alk-1-enes is obtainable by mixing a metallocene complex with a C -C -alk-1-ene in an inert solvent, reacting the resulting mixture in a controlled manner with a compound capable of forming metallocenium ions and diluting the resulting mixture with an inert nonpolar, essentially aliphatic solvent, and also, if desired, applying the catalyst composition to a particulate support material.
