Abstract: Catalyst systems contain metal-ligand complexes according to formula (I): In formula (I), M is Ti, Zr, of Hf; n is 0, 1, 2, or 3; m is 1 or 2; each R 1 and each R 2 is independently chosen from (C 1 -C 40 )hydrocarbyl, (C 1 -C 40 )heterohydrocarbyl, (C 1 -C 40 )aryl, (C 1 -C 40 )heteroaryl, halogen, and -H; R 1 and R 2 are optionally covalently linked to each other; and each R 3 is a hydrocarbon or heterohydrocarbon radical having an identity depending on the value of subscript m. The metal-ligand complexes may be incorporated as procatalysts in catalyst systems for polyolefin polymerization.
