TETRA-FUNCTIONAL LONG-CHAIN BRANCHED ETHYLENE-BASED POLYMERS

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 r...

Zusammenfassung: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.
