More Information
Summary:The present invention relates to an ethylene-α-olefin copolymer comprising monomer units derived from ethylene and monomer units derived from an α-olefin having from 3 to 20 carbon atoms, wherein the copolymer has a melt flow rate of 0.01 to 100 g/10 min, a density of 860 to 970 kg/m3, a molecular weight distribution of 5.5 to 12, and an activation energy of flow of 50 to 100 kJ/mol, and when the maximum take-up rate of the copolymer at 150° C. is represented by MTV150 and the maximum take-up rate of the copolymer at 190° C. is represented by MTV190, MTV150 is 40 m/min or more, and the ratio of MTV150 to MTV190 is 1 or less.
