Abstract: of the disclosure: In the polymerization of propylene and other higher 1olefins, polymers which have a high degree of isotacticity and a narrow distribution of molecular weight are obtained in the presence of a catalyst system composed of a zirconium compound which is stereo-rigid and chiral and a linear or cyclic aluminoxane. In addition,the catalyst system is exceptionally active.

Abstract: - 1 - HOE 87/F 163 Process for the preparation of a 1-olefin polymer If the transition metal component used in an olefin polymerization catalyst is the product of the reaction between a siloxane-substituted metallocene of titanium, zirconium or hafnium and a hydroxyl group-containing support material, for example silicon dioxide, these metallocene catalysts can be employed in existing polymerization plants which are designed for the suspension process.

Abstract: The homopolymerisation of ethylene or the copolymerisation of ethylene with other 1-olefins is carried out using a catalyst which comprises a trialkyl aluminium compound and the entire product from the reaction of a magnesium alkoxide compound with a tetravalent titanium compound and a halogen-containing organoaluminium compound. A polymer having coarse particles and high bulk density is obtained.
