Abstract
Embodiments of this disclosure are directed to ethylene-based polymers. The ethylene-based polymers are polymerized units derived from ethylene, diene, and optionally one or more C-Cα-olefins. The ethylene-based polymer includes a melt strength greater than negative 17 times the log base 10 of the melt index plus 25 ((MS)>−17*log (MI)+25). In the equation, MS is the melt strength in cN and MI is the melt index in g/10 min according to ASTM D1238. The ethylene-based polymer also includes an average g' that is greater than 0.70. The average g′ is an intrinsic viscosity ratio determined by gel permeation chromatography using a triple detector.
