Ethylene-alpha-olefin copolymer and composition, film, laminate and electrical insulating material comprising same

摘要

An ethylene- alpha -olefin copolymer having: (A) a density d of 0.86 to 0.96 g/cm<3>; (B) a melt flow rate MFR of 0.01 to 200 g/10min; (C) a molecular weight distribution Mw/Mn of 1.5 to 4.5; (D) a composition distribution parameter Cb of 1.08 to 2.00; and (E) an orthodichlorobenzene-soluble content X (wt%) at 25 DEG C, a density d (g/cm<3>) and a melt flow rate MFR (g/10min) satisfying that: (i) when the density (d) and the melt flow rate MFR satisfy relationship (I): $the\; orthodichlorobenzene-soluble\; content\; X\; satisfies\; relationship\; (II):$ (ii)\; when\; the\; density\; d\; and\; the\; melt\; flow\; rate\; MFR\; satisfy\; relationship\; (III):$ the\; orthodichlorobenzene-soluble\; content\; X\; satisfies\; relationship\; (IV):$ $$$$
