Propylene polymer compositions comprising:
A) from 70 wt% to 95 wt%, of a random copolymer of propylene with ethylene, containing from 3.5 wt% to 6.5 wt% of ethylene derived units, having a content of fraction insoluble in xylene at 25°C of not less than 93wt%;
B) from 5 wt% to 35 wt%, of a copolymer of propylene with ethylene, containing from 8.5 wt% to 17.0 wt % of ethylene derived units;
the sum A+B being 100;
wherein the melt flow rate ,MFR (ISO 1133 (230° C, 2.16 kg) ranges from 0.6 g/10 min to 20.2 g/10 min. |
