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.

Abstract: Ziegler-Natta catalyst system, contains (a) a titanium-containing solid component derived from a titanium compound, a magnesium compound, a halogenating agent and an electron donor, (b) an aluminium compound and (c) an organosilicon compound of formula R R Si(OR )2 (I) as additional electron donor, in which R = 1-10C alkyl or 3-8C cycloalkyl; R = 2,4,4,6,6-pentamethylheptyl; R = 1-8C alkyl. Also claimed is (i) a process for the production of polymers from 2-10C alk-1-enes by polymerisation for 1-10 hours at 20-150 degrees C and 1-100 bar in presence of this catalyst system; (ii) polymers of 2-10C alk-1-enes obtained by this process; and (iii) film, fibres and mouldings obtained from these polymers.
