    摘要: Multilayer heat-shrinkable films in which the skin layers A consist of a polyolefin selected from: A1) a composition containing 25-45% b.w. of a random copolymer of propylene with ethylene and 55-75% b.w. of a random terpolymer of propylene, ethylene and one or more C4-C10 alpha-olefins; and A2) random copolymer(s) of propylene and one or more C4-C10 alpha-olefins. Core layer B comprises a heterophasic composition comprising: a) 20-60% b.w. of a propylene homopolymer with an isotacticity index higher than 80 or of a propylene crystalline copolymer with ethylene and/or C4-C10 alpha-olefins containing at least 85% b.w. of propylene units and having an isotacticity index of at least 80 or of mixtures thereof and b) 40-80% b.w. of an ethylene copolymer with propylene and/or 1-butene and possibly a diene, containing 20-60% b.w. of ethylene units and completely soluble in xylene at 25° C.

    摘要: Articles, particularly pressure pipes, having high strength as well as high stiffness and very good impact resistance even at low temperatures can be obtained by using a heterophasic polyolefin composition comprising (percent by weight) 70-90% of a random copolymer of propylene with 0.5-6% of 1-hexene, and 10-30% of a polymer of ethylene with a C3-C10 α-olefin and optionally a diene, wherein the polymer of ethylene has an ethylene content higher than 45% and an intrinsic viscosity [η] value from 3 to 5 dl/g.A particular advantage of the present invention is that articles comprising the above heterophasic polyolefin composition show a low ductile to brittle transition temperature (DBTT).
