摘要：
A polypropylene composition made from or containing:
A) from 88.0 wt. % to 98.0 wt. %, of a random copolymer of propylene containing from 0.8 wt. % to 4.8 wt. % of 1-hexene derived units; the random copolymer of propylene having:
a Melt Flow Rate: measured according to ISO 1133 (230° C., 5 Kg) ranging from 0.5 to 4.4 g/10 min; and
B) from 2.0 wt. % to 12.0 wt. % of a terpolymer of propylene ethylene and 1-hexene having a content of ethylene derived units ranging from 35 wt. % to 60 wt.; and a content of 1-hexene derived units ranging from 1 wt. % to 6 wt. %;
wherein the polypropylene composition has a Melt Flow Rate: measured according to ISO 1133 (230° C., 5 Kg) ranging from 0.5 to 5.0 g/10 min.
