    Abstract: Random copolymers (I) of propylene with ethylene and 4-10 carbon (C) alk-1-ene(s), with a melting point of 135 degrees C (by differential scanning calorimetry (DSC) method), are obtained by polymerising the monomers from the gas phase, in the absence of a liquid reaction medium, at 50-100 degrees C and 15-40 bar in the presence of a Ziegler-Natta catalyst system containing (a) solid component containing titanium (Ti), a halogenated magnesium (Mg) compound, an electron donor and an inorganic oxide as carrier, (b) an aluminium (Al) compound and (c) another electron donor compound. The novelty is that the ratio of the partial pressures is adjusted to (20-100):1 for propylene and ethylene and (2.5-20):1 for 4-10 C alk-1-ene(s) and ethylene. Also claimed are: (i) the production of (I) in this way; and (ii) films, fibres or mouldings containing (I).

    Abstract: Moulding materials (I) comprise (A) polymers of propylene and ≤ 20 wt.% other monomers, contg. (B) 0.05-0.4 wt.% mono- or poly-basic carboxylic acid amide(s) with a mol. wt. of 150-600 and (C) 0.1-3.0 wt.% ethylene polymer with ≤ 20 wt.% comonomers, with a density of 0.890-0.945 g/cm and a MFI 190/2.16 of 10-100 g/10 mins.. Also claimed are films and mouldings made from (I), such as injection syringes. Pref. (A) is a polypropylene homopolymer or a copolymer of 90-99.9 wt.% propylene and 0.1-10 wt.% ethylene and/or 4-10C alk-1-ene. (B) is 13-docosenoic acid amide (erucamide) and/or 9-octadecenoic acid amide (oleamide), in amts. of 0.08-0.2 wt.%.
