    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: Propylene polymers (I) contain a matrix of propylene homopolymer and a copolymer of propylene and other alkenes. The novelty is that the polymers satisfy certain condition(s) when separated by tacticity and comonomer distribution of the polymer chain. They are first dissolved in boiling xylene, then the solution is cooled to 25 degrees C at a rate of 10 degrees C/hour. The polymers are separated, into fractions of different solubility at increasing temperature, whilst the matrix remains undissolved on heating the cooled solution to 80 degrees C. The conditions are that the amount of matrix remaining undissolved on further heating is (i) > 20 wt.% at 112 degrees C; (ii) > 8 wt.% at 117 degrees C and/or > 1 wt.% at 122 degrees C. Also claimed are (1) a method of producing (I); and (2) films, fibres or mouldings made from (I).
