Patent ID: 8586675

Claim:
A polyolefin compositions comprising, all percentages being by weight: A) from 70 to 95% of a composition comprising (by weight): A I ) 15-80%, at least one copolymer of propylene selected from the group consisting of: (A I 1) propylene/ethylene copolymers containing 1-7% of ethylene; (A I 2) copolymers of propylene with from 2 to less than 14% of least one C 4 -C 8 alpha-olefin; and (A I 3) copolymers of propylene with ethylene and at least one C 4 -C 8 alpha-olefin, containing 0.5-4.5% of ethylene and 2-6% of C 4 -C 8 alpha-olefins, provided that the total content of ethylene and C 4 -C 8 alpha-olefins in (A I 3) is at most 6.5%; A II ) 20-85% of at least one copolymer of propylene selected from the group consisting of: (A II 1) copolymers of propylene with from 14% to 30% of at least one C 4 -C 8 alpha-olefin; and (A II 2) copolymers of propylene with ethylene and at least one C4-C8 alpha-olefin, containing 0.5-5% of ethylene and 9-30% of C 4 -C 8 alpha-olefins; and B) from 5 to 30% of an elastomeric or plastomeric polyolefin or polyolefin composition.
