Ethylene-based resin and molded object obtained therefrom

摘要

Ethylene-based resin, which exhibits a satisfactorily high melt tension and can provide a molded object excellent in mechanical strength, the ethylene-based resin characterized in simultaneously satisfying the requirements [1] to [5] described below: [1] melt flow rate (MFR) under a loading of 2.16 kg at 190° C. is in the range of 0.1 to 100 g/10 minutes; [2] density (d) is in the range of 875 to 970 kg/m3; [3] ratio [MT/&eegr;*(g/P)] of melt tension [MT(g)] at 190° C. to shearing viscosity [&eegr;*(P)] at 200° C. at an angular velocity of 1.0 rad/sec. is in the range of 1.50×10−4 to 9.00×10−4; [4] sum [(A+B)(/1000C)] of the number of methyl branches [A(/1000C)] and the number of ethyl branches [B(/1000C)] per 1000 carbon atoms measured by 13C-NMR is 1.8 or less; and [5] zero shear viscosity [&eegr;0(P)] at 200° C. and weight-average molecular weight (Mw) measured by GPC-viscosity detector method (GPC-VISCO) satisfy the following relational expression (Eq-1): 0.01×10−13×Mw3.4≦̸&eegr;0≦̸4.5×10−13×Mw3.4  (Eq-1).
