| 摘要 |
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 8.5 wt %, of ethylene derived units, having a content of fraction soluble in xylene at 25° C. comprised between 7.1 wt % and 15.2 wt % and having a melting point higher than 142.0° C.;;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; the melt flow rate, MFR (ISO 1133 (230° C., 2.16 kg).) from 0.6 g/10 min to 20.2 g/10 min. |

1. A propylene polymer composition comprising:
A) from 70 wt % to 95 wt %, of a random copolymer of propylene with ethylene, containing from 3.5 wt % to 8.5 wt %, of ethylene derived units, having a content of fraction soluble in xylene at 25° C. comprised between 7.1 wt % and 15.2 wt % and having a melting point higher than 142.0° C.; 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).) from 0.6 g/10 min to 20.2 g/10 min; |
