Patent ID: 8796385

Claim:
A polyolefin composition consisting of the following components, all percent amounts being by weight: A) 15-40% of a copolymer of propylene with hexene-1 containing from 2.5 to 10% of hexene-1 and having a melt flow rate, measured according to ISO 1133 at 230° C./2.16 kg, from 0.5 to 100 g/10 min., and having a melting point from 125 to 150° C.; and B) 60-85% of a copolymer of ethylene with propylene or a CH 2 ═CHR α-olefin, where R is a C 2 -C 8 alkyl radical, and optionally minor quantities of a diene present in an amount from 1 to 10% by weight, or a copolymer of ethylene with propylene and said α-olefin, and optionally a diene, present in an amount from 1 to 10% by weight, said copolymers containing ethylene in a quantity equal to or lower than 40%, and having a solubility in xylene at room temperature greater than 70%, wherein the polyolefin composition has a melt flow rate from 0.6 to 15 g/10 min, measured according to ISO 1133 at 230° C./2.16 kg.
