Abstract

See full text

A polyethylene composition made from or containing a polyethylene, having the following features:

    1) a density from about 0.930 to about 0.945 g/cm3, determined according to ISO 1183 at 23° C.;2) a ratio of MIF/MIP from about 30 to about 55;3) a MIF from about 3 to about 25 g/10 min.;4) a Mz equal to or greater than about 1,500,000 g/mol; and5) a long-chain branching index, LCBI, equal to or lower than about 0.55, wherein the LCBI is the ratio of the measured mean-square radius of gyration Rg, measured by GPC-MALLS, to the mean-square radius of gyration for a linear PE having about the same molecular weight of 1,000,000 g/mol.
