Abstract

An ethylene-.alpha.-olefin copolymer composition comprising two ethylene-.alpha.-olefin copolymers which are different in density, intrinsic viscosity and the number of short chain branching per 1000 carbon atoms. Extrusion processed materials, injection molded materials and films obtained from said composition are excellent in strength.
