Patent ID: 10577440

Abstract:
A radically coupled polymer having a density of from about 0.915 g/ml to about 0.975 g/ml characterized by a crossover modulus measured in Pascals (Pa) that is equal to or less than ymn where ymn=180,000e−0.15x and x is the number average molecular weight of the radically coupled polymer divided by 1,000. An ethylene polymer having a level of short chain branching ranging from about 0 to about 10 mol. %; a level of long chain branching ranging from about 0.001 LCB/103 carbons to about 1.5 LCB/103 carbons as determined by SEC-MALS; and characterized by a crossover modulus measured in Pa that is equal to or less than ymn where ymn=180,000−0.15x and x is the number average molecular weight of the radically coupled polymer divided by 1,000.
