摘要：
A propylene polymer composition comprising: A) 70-94% wt of a propylene-ethylene copolymer comprising from 2.5 to 5% wt of ethylene derived units; and B) 6-30% wt of a second propylene-ethylene copolymer comprising from 35 to 60% wt of ethylene derived units. Said propylene polymer composition having a MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230° C. and 2.16 kg load) from 0.1 to 5 g/10 min, and an Intrinsic Viscosity of the fraction soluble in xylene [XSIV] at room temperature: from 1 to 4.5 dl/g.Such propylene polymer composition being particularly suitable for the production of injection moulded articles and in particular of films.
