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

摘要

A laminate containing a polyolefin resin composition containing ethylene-alpha-olefin copolymer having: (A) a density d of 0.86 to 0.96 g/cm3; (B) a melt flow rate MFR of 0.01 to 200 g/10 min; (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° C. a density of d (g/cm3) and a melt flow rate MFR (g/10 min) 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):
