Abstract: The prodn. of bridged half-sandwich complexes of formula (I) comprises reacting cyclopentadienides of formula (II) with aziridines (III) and then reacting the ligand systems obtd. (IV) with metallating agents and MXn+2. M = Sub-gp. IV or V metal or lanthanide; X = halo, H, 1-10C alkyl, 3-10C cycloalkyl, 6-15C aryl, 7-15C alkylaryl or -OR (with R = 1-10C alkyl, 6-15C aryl, or alkaryl, aralkyl, fluoroalkyl or fluoroaryl with 1-10C alkyl gps. and 6-20C aryl gps.). n = valency of M minus 2; R = H, 1-10C alkyl, 3-10C cycloalkyl (opt. substd. with 1-10C alkyl), 6-15C aryl, (6-20C aryl)-(1-10C alkyl) or -Si(R )3 (with R = 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl); R -R = as for R , opt. with two adjacent gps. forming a 4-15C cyclic gp.

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.
