Patent ID: 8835568

Claim:
A propylene polymer composition comprising (percent by weight): A) 65%-85% of a propylene copolymer containing from 2.0% to 5.0% of ethylene derived units having MFR L (Melt Flow Rate according to ASTM 1238, condition L,) from 0.5 to 50 g/10 min and a melting temperature Tm ranging from 146° C. to 155° C.; and B) 15%-35%, of a copolymer of ethylene and propylene, wherein component B) has an ethylene content from 74% to 87%; the composition having an intrinsic viscosity of a fraction soluble in xylene ranging from 0.8 to 1.2 dl/g, and an elongation at break ranging from 650% to 1200%.
