摘要
Propylene polymer compositions comprising (percent by weight): A) from 70 to 90% of a random copolymer of propylene with ethylene, containing from 1 to 6% of ethylene, having a content of fraction insoluble in xylene at room temperature (about 23° C.) of not less than 93%; B) from 10% to 30% of a copolymer of propylene with ethylene, containing from 8 to 18% of ethylene; wherein the ratio (B)/C2B of the percent by weight of (B), with respect to the total weight of (A) and (B), to the percent by weight of ethylene in (B), with respect to the total weight of (B), represented in the above formula by C2, is 2.5 or lower.
