Claim 0:
1. A polypropylene composition comprising:
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, based upon the total weight of the random copolymer of propylene, wherein the random copolymer of propylene has 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, wherein the terpolymer consists of propylene, ethylene and 1-hexene, and wherein the terpolymer has a content of ethylene derived units ranging from 35 wt. % to 60 wt. %, based upon the total weight of the terpolymer, and a content of 1-hexene derived units ranging from 1 wt. % to 6 wt. %, based upon the total weight of the terpolymer,
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, and
wherein the sum of the amounts of A) and B) is 100.
