Abstract: The Ziegler-Natta type catalyst system (I) comprises as active constituents: (a) a Ti-contg. solid component comprising a Ti cpd., a Mg cpd., a halogen, silica gel as support and a carboxylic ester as electron donor; (b) an Al cpd. as cocatalyst; and opt (c) a further electron donor cpd. as a further cocatalyst, where the silica gel has a mean particle dia. of 5-200 mu m, a mean particle dia. of the prim. particles of 1-10 mu m, and voids or channels having a mean dia. of 1-10 mu m whose macroscopic proportion in the total particle is 5-20 vol.%. Also claimed are: (1) prodn. of (I) comprising reacting (a), (b) and opt. (c) at 0-150 deg C and 1-100 bar pressure; (2) prepn. of propylene polymers, comprising polymerising propylene and opt. comonomers at 20-150 deg C and 1-100 bar pressure in the presence of (I); and (3) a propylene polymer, partic. a homopolymer, so obtd.
