Patent ID: 8569418

Claim:
An article comprising a polyolefin composition comprising, in percent by weight referred to the sum of component 1) and 2): (1) 75-85 wt % of a propylene homopolymer or copolymer of propylene with at least one of ethylene and C 4 -C 10 α-olefin(s), the homopolymer or copolymer having melting temperature equal to or higher than 150° C., and (2) 15-25% of a copolymer of ethylene with at least one C 4 -C 10 α-olefin containing from 20 to 30% of said C 4 -C 10 α-olefin; said composition having (i) a value of MFR at 230° C., 2.16 kg of from 5 to 10 g/10 min, (ii) a total content of ethylene of from 10 to 20%, (iii) a total content of C 4 -C 10 α-olefin of from 2 to 8%, (iv) a ratio XStot/XSm of the total fraction soluble in xylene at room temperature to the fraction soluble in xylene at room temperature of the component (1) of from 5 to 15, and (v) a value XSIVtot of the intrinsic viscosity of the total fraction soluble in xylene at room temperature of 1.5 dl/g.
