ABSTRACT OF THE DISCLOSURE Catalyst Compositions and Process for Preparing Polyolefins Catalyst compositions comprising both metallocene complexes having polymerisable groups and polymerization catalysts eg Ziegler- Natta 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.
