and electrical insulating material comprising same
摘要:
A polyolefin resin composition containing an ethylene-.alpha.-olefin copolymer having: (A) a density d of 0.86 to 0.96 g/cm.sup.3 ; (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.degree. C. a density of d (g/cm.sup.3) and a melt flow rate MFR (wt %) satisfying that: (i) when the density (d) and the melt flow rate MFR satisfy relationship (I):d-0.008.times.logMFR.gtoreq.0.93 (I)the orthodichlorobenzene-soluble content X satisfies relationship (II):X
