Abstract:
1. An ethylene-α-olefin copolymer comprising a repeating unit derived from ethylene and a repeating unit derived from hexene, wherein said copolymer has a melt flow rate (MFR) of 0.1 to 5 g/10 minutes, a density of 920 to 960 kg/m 3 , a molecular weight distribution (Mw/Mn) of 3 to 7, and a ratio (η* 0.1 /η* 100 ) of a dynamic complex viscosity (η* 0.1 ) at a temperature of 190° C. and an angular frequency of 0.1 rad/s, to a dynamic complex viscosity (η* 100 ) at a temperature of 190° C. and an angular frequency of 100 rad/s of 15 to 60.
