Abstract: A polyolefϊn composition comprising, in percentage by weight based on the weight sum of the components (al), (a2) and (b): al) 16-78 % of a propylene homopolymer or copolymer containing at most 15% of ethylene and/or C4-C10 α-olefm(s), having an isotactic index over 80%; and a2) 6-44% of a copolymer of ethylene with one or more C
4 -C
10 α-olefm(s) containing from 10 to 40%, preferably from 15 to 35%,of said C
4 -C
10 α-olefm(s); b) 3-70% of a butene-1 (co)polymer having: - a content of butene-1 derived units of 80% wt or more, - flexural modulus (MEF) of 60 MPa or less. The polyolefϊn composition exhibits good impact resistance, excellent whitening resistance and relatively low stiffness combined with good optical properties suitable for injection and blow molding, thermoforming and film application.

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.
