Abstract:
1. A polyolefin composition comprising (percentage by weight): (A) 5% to 80% of a butene-1 polymer or polymer composition containing from 4% to 25% of ethylene and comprising a copolymer fraction (i) present in an amount from 50% to 75% with respect to the weight of (A), said fraction (i) containing from 6.2% to 15% by weight of ethylene, said polymer or polymer composition having a content of fraction soluble in xylene at 0° C. of from 50% to 100% and a Flexural Modulus (measured according to ISO 178) from 15 to 300 MPa; and (B) 20% to 95% of a propylene homopolymer having a content of fraction insoluble in xylene at room temperature of at least 93%, wherein the flexural elastic modulus according to ISO 178 of the component (B) is from 1500 to 2500 MPa.
