Abstract:
1. A propylene polymer composition comprising (percent by weight): A) from 60 to 90% of one or more propylene copolymer(s) having a content of moiety insoluble in xylene at room temperature of not less than 85%, selected from the group consisting of (A1) random copolymers of propylene with ethylene containing from 1 to 7%, of ethylene; (A2) copolymers of propylene with one or more C B) from 10 to 40% of a copolymer of propylene containing from 8 to 30% of ethylene and optionally 1-10% of a C wherein the propylene polymer composition has a haze value lower than 20%, a flexural modulus lower than 500 MPa, an MFR(2) value of from 3 to 30 g/10 min obtained by subjecting to degradation a precursor composition comprising the same copolymers (A) and (B) in the above said proportions having an MFR(1) value of from 0.1 to 5 g/10 min, with a ratio MFR (2) to MFR (1) of from 1.5 to 20.
