| description | PROBLEM TO BE SOLVED: To provide an ethylenic polymer having excellent moldability and easy openability, a thermoplastic resin composition containing the ethylenic polymer, a molded article and a film produced therefrom and a laminate film containing the film. SOLUTION: The ethylenic polymer satisfies the following requirements (I) to (V) at the same time. (I) The ratio [MMe+Et/Mall] of the content [MMe+Et(mol%)] of the methyl branches and the ethyl branches determined by13C-NMR to the content [Mall(mol%)] of all branches determined by13C-NMR is 0.30-1.00; (II) the MFR (190°C, 2.16 kg-load) is 0.1-100 g/10 min; (III) the density is 875-970 kg/m3; (IV) the ratio [MT/η*(g/p)] of the melt tension (MT(g), 190°C) to the shear viscosity [η*(P), 200°C, 1.0 rad/sec] is 1.50×10-4to 9.00×10-4; and (V) the zero shear viscosity [η0(P), 200°C] and the weight-average molecular weight (Mw) determined by a GPC-viscosity detector method satisfy the relationship of 0.01×10-13×Mw3.4≤η0≤4.50×10-13×Mw3.4.
