Abstract
Embodiments of this disclosure are directed to ethylene-based polymers. The ethylene-based polymer are polymerized units derived from ethylene, diene, and optionally, one or more C3-C12 α-olefins. The ethylene-based polymer includes a melt viscosity ratio (V0.1/V100) at 190 C greater than 20. The V0.1 is the viscosity of the ethylene-based polymer at 190 C at a frequency of 0.1 radians/second, and the V100 is the viscosity of the ethylene-based polymer at 190 C at a frequency of 100 radians/second. Additionally, the ethylene-based polymer includes an average g greater than 0.86, where the average g′ is an intrinsic viscosity ratio determined by gel permeation chromatography using a triple detector.
