Abstract: The polymeric composition of the present invention is a polyolefin composition comprising (percent by weight): 1) 10-60% of a copolymer of propylene and hexene-1 wherein said copolymer comprises from 0.2 to 10 % of recurring units derived from hexene-1; and 2) 10-85% of a propylene polymer selected from propylene homopolymer and a polymer of propylene with 0.1-10% of an α-olefin selected from ethylene, a C4-C10 a-olefin, hexene-1 excluded, and a mixture thereof, said propylene polymer being insoluble in xylene at ambient temperature in an amount over 85% and having a Polydispersity Index ranging from 3 to 20; and 3) 5-30% of a copolymer of ethylene with a C3-C10 α-olefin and optionally a diene, having an ethylene content ranging from 15 to 60% and an intrinsic viscosity value of at least 1 dl/g. Pipe systems and sheets produced from said composition show an optimal balance of mechanical properties.

Abstract: A single- or multilayer threaded pipe, wherein at least one layer is produced from a polyolefin composition comprising (percentages express on the basis of the sum of components (A) and (B)): (A) 65-90 wt% of a heterophasic polypropylene composition comprising (percentages expressed on the basis of the polypropylene composition): (1) 65-95 wt% of a propylene polymer selected from propylene homopolymer and co- and terpolymers of propylene with a comonomer selected from ethylene, a C4-C10 alpha-olefin and a mixture thereof, said polymer containing 0.1-10 wt% of comonomer units, being insoluble in xylene at 25°C in an amount over 85 wt%, having a polydispersity index ranging from 4 to 13 and an intrinsic viscosity ([η]1) value of over 2.2 dl/g; and (2) 5-35 wt% of an olefin polymer of ethylene with propylene or a C4-C10 alpha- olefin having an ethylene content ranging from 15 to 85 wt% and an intrinsic viscosity of the fraction soluble in xylene ([η]2) of at least 1.4 dl/g; wherein the ratio of the intrinsic viscosity value of propylene polymer (1) to that of olefin polymer (2) ([η]1/[η]2) ranges from 0.45 to 1.6; and (B) 10-35 wt% of a at least one filler selected among calcium carbonate, talc, wollastonite or mixtures thereof.

Abstract: Articles, in particular non-pressure mono- or multi-layer pipes, prepared by extrusion, moulding and combination thereof, comprising a heterophasic polyolefin composition comprising (1) 65-95% of a crystalline propylene polymer 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 value ([η]l) of over 2.2 dl/g, and (2)5-35% of an elastomeric olefin polymer of ethylene with a C3-C10 α-olefin having an ethylene content ranging from 15 to 85% and an intrinsic viscosity value ([η]2) of at least 1.4 g/ml. The [η]1/[η]2 ratio ranging from 0.45 to 1.6. The articles typically have modulus of elasticity in tension higher than 2000 MPa. The invention also relates to the said heterophasic polyolefin composition and an extrusion process for producing the said articles.
