Abstract
The invention provides a solution polymerization process to form an ethylene/α-olefin/nonconjugated polyene interpolymer, said process comprising polymerizing ethylene, an α-olefin, and a nonconjugated polyene in at least one reactor in the presence of a catalyst selected from Formula I, as described herein; and wherein the polymerization is conducted in a continuous process; and wherein the interpolymer has a rheology ratio (V0.1/V100 at 19° C.) greater than, or equal to, 20.
