    摘要: 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 α-olefin of 3 ∼ 20 carbon atoms, said ethylene copolymers having

    [A] a density of 0.85 ∼ 0.92 g/cm 3 ,
    [B] an intrinsic viscosity [η] as measured in decalin at 135°C of 0.1 ∼ 10 dl/g,
    [C] a ratio ( M ¯ w/ M ¯ n) of a weight average molecular weight ( M ¯ w) to a number average molecular weight ( M ¯ n) as measured by GPC of 1.2 ∼ 4, and
    [D] a ratio (MFR 10 /MFR 2 ) of MFR 10 under a load of 10 kg to MFR 2 under a load of 2.16 kg at 190°C of 8 ∼ 50, and being narrow in molecular weight distribution and excellent in flowability.
