Abstract

In accordance with the present invention, there are provided ethylene copolymers composed of structural units (a) derived from ethylene and structural units (b) derived from .alpha.-olefin of 3 ? 20 carbon atoms, said ethylene copolymers having [A] a density of 0.85 ? 0.92 g/cm3, [B] an intrinsic viscosity [?] as measured in decalin at 135°C of 0.1 ? 10 dl/g, [C] a ratio (Mw/Mn) of a weight average molecular weight (Mw) to a number average molecular weight (Mn) as measured by GPC of 1.2 ? 4, and [D] a ratio (MFR10/MFR2) of MFR10 under a load of 10 kg to MFR2 under a load of 2.16 kg at 190°C of 8 ? 50, and being narrow in molecular weight distribution and excellent in flowability.
