Zusammenfassung:	Catalyst Compositions and Process for Preparing Polyolefins Catalyst compositions comprising both metallocene complexes having polymerisable groups and polymerization catalysts eg ZieglerNatta may be used for the preparation of polyolefins. The catalyst compositions may comprise the metallocene complex in the form of a polymer and may suitably be supported on inorganic supports. Polymers having a wide range of molecular weights and comonomer distributions may be prepared by use of the catalyst compositions. Preferred metallocene complexes are zirconium complexes in which the polymerisable group is vinyl.
