摘要： Polymer compositions include an interpolymer of ethylene, an α-olefin, and a nonconjugated polyene; and from 10% to 40% by weight oil. The polymer composition has a Mooney viscosity from 20 to 70. The interpolymer may include from 66% to 75% by weight monomer units derived from ethylene; and from 0.5% to 10% by weight monomer units derived from the nonconjugated polyene. The neat interpolymer may have: a weight-average molecular weight Mw from 250 kDa to 300 kDa; a Mooney viscosity from 50 to 200; a rheology ratio V0.1/V100 less than 30; a ratio of molecular weight to low-shear viscosity Mw/V0.1 greater than 4.0; a polydispersity index from 2.0 to 3.5; and a tan δ at 0.1 rad/sand 190° C. greater than 2.0. The polymer compositions may be in the form of pellets having desirable flow characteristics. Thermoplastic vulcanizates may include the polymer compositions. Articles may include the thermoplastic vulcanizates.
