Abstract: A process for preparing a supported transition metal catalyst comprising a particulate organic or inorganic support material, a transition metal complex and a compound capable of forming metallocenium ions comprises the following process steps:a) contacting a solution of a compound capable of forming metallocenium ions with a second solvent in which this compound is only sparingly soluble, in the presence of the support material,b) removing at least part of the solvent from the support material andc) contacting a solution of a mixture of a compound capable of forming metallocenium ions and a transition metal complex with a second solvent in which this mixture is only sparingly soluble, in the presence of the support material obtained as described in a) and b).

Abstract: Ziegler-Natta type catalyst system (ZNC), containing (a) a titanium-based solid component containing compounds of Ti and magnesium, a halogen, an inorganic oxide support (IOS) and a carboxylate ester as electron donor, (b) an aluminium compound and (c) optionally another electron donor, in which the oxide (IOS) has a pH of 1-6, an average particle diameter of 5-200 microns and an average primary particle diameter of 1-20 mu m, and contains pores or channels with an average diameter of 0.1-20 mu m in amounts of 5-30 vol%. Also claimed is (i) a process for the production of ZNC by interacting components (a), (b) and (c) together at 0-150 degrees C and 1-100 bar; (ii) a process for the production of polymers of 2-20C alk-1-enes by polymerisation of the alkene (preferably propylene) and optionally other comonomers at 20-150 degrees C and 1-100 bar in presence of (ZNC); (iii) polymers of propylene obtained by this process.
