Abstract
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and at least two kinds of specific metallocene compounds (b), and a low-density polyethylene obtained by high-pressure radical polymerization. The ethylene/.alpha.-olefin copolymer compositions of the invention are excellent in moldability. From these copolymer compositions, films having high transparency and high mechanical strength can be produced.
