Abstract:
1. A propylene polymer composition comprising: A) from 70 wt. % to 95 wt. %, of a random copolymer of propylene and ethylene derived units, wherein the random copolymer of propylene and ethylene contains from 1.5 wt. % to 4.5 wt. %, of ethylene derived units based upon the total weight of the random copolymer of propylene and ethylene, and has a content of fraction insoluble in xylene at 25° C. of not less than 93 wt. %; B) from 5 wt. % to 35 wt. %, of a copolymer of propylene and ethylene derived units, wherein the copolymer of propylene and ethylene contains from 7.0 wt % to 17.0 wt % of ethylene derived units based upon the total weight of the copolymer of propylene and ethylene; wherein the sum A+B is 100; wherein the propylene polymer composition has a melt flow rate, MFR (ISO 1133 (230° C., 2.16 kg)) ranges from 55 to 130 g/10 min; and wherein the relation (I) is fulfilled: wherein XS is the wt % of xylene soluble content at 25° C. of the total composition; C2A is the wt % of ethylene derived units content of component A; MFR is the melt flow rate of the total composition; C2B is the wt % of ethylene derived units content of component B.
