Abstract:
1. Articles prepared by extrusion, moulding and combinations thereof, comprising a heterophasic polyolefin composition comprising (percent by weight): (1) 65-95% of a crystalline propylene homopolymer, said crystalline propylene homopolymer being insoluble in xylene at ambient temperature in an amount over 85% and having a polydispersity index ranging from 4 to 13 and an intrinsic viscosity ([η]) value of over 2.2 dl/g; and (2) 5-35% of an elastomeric olefin polymer of ethylene with a C wherein a ratio of the intrinsic viscosity value of the crystalline propylene homopolymer (1) to that of elastomeric olefin polymer (2) ranges from 0.45 to 1.6.
