Claim Text:
1. 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 metal-ligand complex selected from Formula I: wherein: M is a metal of any one of Groups 3 to 6 of the Periodic Table of the Elements (e.g., Group 4), the metal M being in a formal oxidation state of +2, +3, +4, +5, or +6; n is an integer of from 0 to 5, wherein when n is 0, X is absent (i.e., (X)n is absent); each X, independently, is a monodentate ligand that is neutral, monoanionic, dianionic, trianionic, or tetraionic; or two X are taken together to form a bidentate ligand that is neutral, monoanionic, or dianionic; X and n are chosen in such a way that the metal-ligand complex of formula (I) is, overall, neutral; each Z, independently, is O, S, N(C1-C40)hydrocarbyl, or P(C1-C40)hydrocarbyl; L is (C1-C40)hydrocarbylene or (C1-C40)heterohydrocarbylene, wherein the (C1-C40)hydrocarbylene has a portion that comprises a 1-carbon atom to 18-carbon atom linker backbone, linking the Z atoms in formula (I) (to which Z atoms L is bonded) and the (C1-C40)heterohydrocarbylene has a portion that comprises a 1-atom to 18-atom linker backbone, linking the Z atoms in formula (I), wherein each of the from 1 to 18 atoms of the 1-atom to 18-atom linker backbone of the (C1-C40)heterohydrocarbylene independently is a carbon atom or heteroatom, wherein each heteroatom independently is O, S, S(O), S(O) each of R at least one of R optionally two or more R groups (from R at least one of R at least one of R each of R optionally two or more carbazole R groups (e.g. R each of the aforementioned hydrocarbyl (e.g., the sum of carbon atoms in R each R wherein the polymerization is conducted in a continuous process; and wherein interpolymer has a rheology ratio (V0.1/V100 at 190° C.) greater than, or equal to, 20.
