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 that is equal to or less than ymn where ymn=18000e−0.15x and x is the number average molecular weight of the radically coupled polymer. 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 that is equal to or less than ymn where ymn=18000e−0.15x and x is the number average molecular weight of the radically coupled polymer.

Abstract: An ethylene polymer having a density greater than about 0.930 g/ml and 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. An ethylene polymer having a level of short chain branching ranging from about 0 to about 10 mol. % and 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. An ethylene polymer having a polydispersity index ranging from about 8 to about 25 and 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.
