Abstract: Ethylene-based polymers comprise reaction products 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, the ethylene-based polymer having: an Mw/Mw0 greater than 1.20. The Mw0 is the 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 polyene comonomer, under the defined polymerization reaction conditions; and a 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.

Abstract: Embodiments of this disclosure include polymers comprising the polymerized product of ethylene, at least one diene comonomer, and optionally at least one C3 to C14 comonomer. The polymer comprises tri -functional long-chain branches resulting from the diene that occur at a frequency of at least 0.03 per 1000 carbon atoms of the polymer. The diene has a structure according to formula (I):

Abstract: Ethylene-based polymers of this disclosure include a melt viscosity ratio (V0.1/V100) at 190° C. of at least 10, where V0.1 is the viscosity of the ethylene-based polymer at 190° C. at a shear rate of 0.1 radians/second, and V100 is the viscosity of the ethylene-based polymer at 190° C. at a shear rate of 100 radians/second; and a 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.
