Ethylene-based copolymers having unusual viscosity performance are described, particularly ethylene-based polymers having about 80.0 to 99.0 wt.% of polymer units derived from ethylene and about 1.0 to about 20.0 wt.% of polymer units derived from one or more C3 to C20 α-olefin comonomers; the ethylene-based polymer having a local maximum loss angle at a complex modulus, G*, of 2.50x104 to 1.00x106 Pa and a local minimum loss angle at a complex modulus, G*, of 1.00X104 to 3.00*x104 Pa. The invention also includes articles, such as films, produced from such polymers and methods of making such articles. |
