This invention relates to a polymerization method comprising contacting at least one olefin monomer, at least one polar monomer, an optional activator, and a catalyst compound represented by the formula: wherein M is selected from groups 3-11 of the periodic table; L<SUP>1 </SUP>represents a formal anionic ligand, L<SUP>2 </SUP>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, Ar<SUP>0 </SUP>is arene, R<SUP>1</SUP>-R<SUP>4 </SUP>are, each independently, selected from hydrogen, hydrocarbyl, substituted hydrocarbyl or functional group, provided however that R<SUP>3 </SUP>and R<SUP>4 </SUP>do not form a naphthyl ring, N is nitrogen and O is oxygen.
