Abstract
This invention relates to a compound represented by the formula: wherein M is selected from groups 3–11 of the periodic table; L1 represents a formal anionic ligand, L2 represents a formal neutral ligand, a is an integer greater than or equal to 1; b is greater than or equal to 0; c is greater than or equal to 1, E is nitrogen or phosphorus, Ar0 is arene, R1–R4 are, each independently, selected from hydrogen, hydrocarbyl, substituted hydrocarbyl or functional group, provided however that R3 and R4 do not form a naphthyl ring, N is nitrogen and O is oxygen. This invention further relates to a process to oligomerize and/or polymerize unsaturated monomers using the above compositions, optionally combined with an activator.
