Abstract
An ethylene-α-olefin copolymer comprising a repeating unit derived from ethylene and a repeating unit derived from an α-olefin having 3 to 20 carbon atoms, wherein a melt flow rate (MFR) is 0.01 to 100 g/10 minutes, a density is 860 to 970 kg/m, a molecular weight distribution (Mw/Mn) is 2 to 8, and a ratio (η*/η*) of a dynamic complex viscosity (η*) at a temperature of 190° C. and an angular frequency of 0.1 rad/s, to a dynamic complex viscosity (η*) at a temperature of 190° C. and an angular frequency of 100 rad/s is 15 to 100 is excellent in balance between mechanical strength and processability.
