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: Gas phase homo- or copolymerisation of 2-8C alk-1-enes with a Ziegler-Natta or metallocene catalyst system is carried out in a stirred bed of finely-divided polymer, with addition of the catalyst solid (I) containing transition metal with the alkene. The novelty is that (I) is introduced into the reactor with (part of) the alkene through (almost) vertical pipe(s) projecting down into the gas space and ending above the stirred powder bed. Also claimed is the apparatus used. Preferably the vertical distance between the pipe(s) and the surface of the bed is

Abstract: Statistical propylene copolymers with 2-10C alk-1-ene comonomer (alkene) units are claimed, obtained by polymerisation of propylene and alkene at 50-100 degrees C and 15-40 bar with a mean residence time of 0.5-5 hrs., in presence of a Ziegler-Natta catalyst with: (a) a titanium-containing solid component containing a magnesium compound, a halogen, a silica gel support and a carboxylate ester as electron donor; plus (b) an aluminium compound; and (c) another electron donor as cocatalysts. The silica gel support has an average particle diameter of 5-200 mu m and an average primary particle diameter of 1-10 mu m, and contains 5-20 vol% of pores or channels with an average diameter of 1-10 mu m. Also claimed is a process for the production of propylene copolymers.
