1. A composition comprising an ethylene/α-olefin/non-conjugated diene interpolymer, which has the following properties: an Mz(abs)/Mz(Conv) value greater than 1.35; an Mz(BB)/Mw(abs) value greater than 1.6; and a non-conjugated diene content less than 10 weight percent, based on the total weight of the interpolymer; a viscosity ratio (η0.1/η100), at 190° C., from 70 to 300; and a gel content less than 3 weight percent; and
wherein the ethylene/α-olefin/non-conjugated diene interpolymer is formed by reacting at least the following: a base ethylene/α-olefin/non-conjugated diene interpolymer and a coupling agent, and wherein the ethylene/α-olefin/non-conjugated diene interpolymer has a percent change in melt viscosity (0.1 rad/sec, 190° C.) greater than 130%, and a Mooney viscosity (ML 1+4 at 125° C.) greater than 60, and wherein the base ethylene/α-olefin/non-conjugated diene interpolymer has the following properties: an Mz(abs)/Mz(Conv) value less than 1.3; an Mz(BB)/Mw(abs) value greater than 1.6 but less than 2.5; and an Mw(abs) value less than 350,000 g/mole. |
