Abstract
An ethylene copolymer composition comprising an ethylene/α-olefin copolymer, A-4, of ethylene with an α-olefin of 3 to 20 carbon atoms in an amount of 65-98% by weight, whose melt tension, MT, at 190° C. and MFR satisfy the relation MT>2.2×MFR, and at least one crystalline polyolefin, B-2, in an amount of 1-40% by weight selected from the group consisting of, B-I, an ethylene homopolymer or a copolymer of ethylene with an α-olefin of 3 to 20 carbon atoms, prepared using a non-metallocene type catalyst, B-II, a propylene hompolymer or a copolymer of propylene with at least one olefin selected from ethylene and an α-olefin of 4 to 20 carbon atoms, and, B-III, a homopolymer of an α-olefin of 4 to 20 carbon atoms or a copolymer of α-olefins of 4 to 20 carbon atoms, and articles made from the composition.
