Claim Text:
1. A propylene polymer composition comprising (percent by weight): A) 68%-80%, of a propylene homopolymer having a Polydispersity Index (P.I.) value of from 4.7 to 10 and MFR L (Melt Flow Rate according to ISO 1133, condition I, i.e. 230° C. and 216 kg load) from 12 to 25 g/10 min; B) 20%-32%, of a copolymer of propylene containing from 40.1% to 42.5% extremes included of ethylene derived units; the propylene polymer composition having: (i) an intrinsic viscosity of the fraction soluble in xylene at 25° C. between 3 and 6 dl/g, (ii) an Izod impact strength measured at 23° C. from between 50 and 60 kJ/m (iii) an Izod impact strength measured at 0° C. between 25 and 40 kJ/m (iv) an Izod impact strength measured at −20° C. between 10 and 30 kJ/m (v) a flexural modulus between 900 and 1300 MPa, and (vi) a MFR L from 4 to 12 g/10 min.
