Abstract

A polyethylenic resin composition comprising: at least one high density polyethylenic resin selected from (a) a high density polyethylenic resin (Resin A) and (b) a modified high density polyethylenic resin as derived by grafting on the Resin A a monomer of unsaturated carboxylic acid or its derivative (Resin B), at least one linear low density polyethylenic resin selected from (c) a linear low density polyethylenic resin (Resin C) and (d) a modified linear low density polyethylenic resin as derived by grafting on the Resin C the monomer as described in (b) above (Resin D), and (e) a linear very low density polyethylenic resin (Resin E) having a density (g/cm.sup.3) of at least 0.890, but less than 0.910, and a melting point of 110.degree. to 125.degree. C. This polyethylenic resin composition is excellent in fuel oil resistance, low temperature impact resistance, and heat resistance, and provides a material having affinity or adhesive properties to various resinous and metallic materials.
