Claim 0:
1. An ethylene-based polymer comprising a reaction product of polymerizing ethylene monomer, at least one diene or polyene comonomer, and optionally at least one C3 to C14 comonomer under defined polymerization reaction conditions, wherein the ethylene-based polymer has:
an Mw/Mw0 greater than 1.20, where Mw is the weight-average molecular weight of the ethylene-based polymer as determined from a gel permeation chromatography curve of the ethylene-based polymer acquired by refractive index chromatography, and Mw0 is initial weight-average molecular weight of a comparative ethylene-based polymer by gel permeation chromatography, the comparative ethylene-based polymer being a reaction product of polymerizing ethylene monomer and all C3 to C14 comonomers present in the ethylene-based polymer, if any, without the at least one diene or polyene comonomer, under the defined polymerization reaction conditions; and
a high molecular weight tail quantified by an MWD area metric, ATAIL, and ATAIL is less than or equal to 0.04 as determined by gel permeation chromatography using a triple detector.
