Abstract: Catalyst systems for olefin polymerization include a metal-ligand complex of a general formula (I). The metal-ligand complex of formula (I) is a transition metal complex of titanium, zirconium, or hafnium, in which the transition metal is coordinated with a biaryl phenoxy ligand structure. Olefin polymerization processes include contacting ethylene and optionally one or more (C3-C12) alpha-olefins in the presence of the catalyst system to produce an ethylene-based polymer or copolymer.
