Patent ID: 8735498

Claim:
A polyolefin composition comprising: (A) from 5 to 45% by weight of a polypropylene component comprising a propylene homopolymer or a propylene copolymer with another a-olefin or combinations thereof, said polypropylene component containing at least 85% by weight of propylene, and having a solubility in xylene at room temperature lower than 20% by weight; (B) from 82 to 45% by weight of a polyolefin component comprising a copolymer or a composition of copolymers of ethylene with at least one other a-olefin, containing from 15% by weight to 70% by weight of ethylene, said polyolefin component having a solubility in xylene at room temperature greater than 60% by weight; and (C) from 2.5 to 25% by weight of a butene-1 (co)polymer having: a content of butene-1 derived units of at least 75 wt. %; a flexural modulus of at most 60 MPa.
