Abstract

A composition comprising an ethylene/alpha-olefin interpolymer that comprises the following properties: a) a total unsaturation/1000C≥0.30; b) a molecular weight distribution (MWD)≤3.0; c) a TGIC broadness parameter B≤8.0. A solution polymerization process to prepare an ethylene/alpha-olefin/interpolymer, said process comprising polymerizing, in one reactor, at a reactor temperature ≥150° C., a reaction mixture comprising ethylene, an alpha-olefin, a solvent, and a metal complex as described herein. A method to determine the TGIC broadness parameter Bof a polymer composition comprising one or more olefin-based polymers.
