An ethylene copolymer composition which exhibits suitable elasticity in elongation and pressure-sensitive adhesiveness and is excellent in transparency, strengths, strain recovery, blocking resistance and processability and free from chlorine; and films, sheets, pipes, tubes and other articles molded from the composition. The composition comprises 10 to 90 wt.% of (A) a copolymer comprising ethylene and a monomer selected from among aromatic vinyl compounds and .alpha.-olefins and having a crystallinity of 10 % or above but below 90 % and an intrinsic viscosity [A] of 1 to 10 dl/g, and 10 to 90 wt.% of (B) an ethylene homopolymer or a copolymer comprising ethylene and a monomer selected from among aromatic vinyl compounds and .alpha.-olefins and having a crystallinity of higher than 10 % but up to 90 % and an intrinsic viscosity [B] of 0.1 to 2 dl/g, at least either of the components (A) and (B) containing an aromatic vinyl compound as the comonomer, the ratio of the crystallinity of the component (A) to that of the component (B) being less than 1, and the [A] to [B] ratio exceeding 1. |
