Abstract

PURPOSE: To prepare the title composition having excellent impact strength, environmental crack resistance, and moldability, by blending a high molecular weight ethylene copolymer containing a specific amount of copolymer component, and a low molecular weight ethylene homopolymer.
CONSTITUTION: A composition having a melt index of <0.05, and composed of (A) 30W70 parts by weight of a polyolefin having a density of 0.910W0.930, a viscosity-average molecular weight of 300,000W700,000, the ratio of weight-average molecular weight/number-average molecular weight of 2W10, and composed of 97.5W99.5mol% of ethylene and 2.5W0.5mol% of other α-olefin such as propylene, butene-1 and hexene-1, and (B) 70W30 parts of an ethylene homopolymer having a density of 0.970W0.977, a viscosity-average molecualr weight of 10,000W40,000, and the ratio of weight-average molecular weight/number-average molecular weight of 2W10, wherein the ratio of the viscosity-average molecular weight of the A polymer to that of the B polymer is 15W55, pref. 20W50.
