Activation with AlMe at low temperature converts half-metallocene complexes of tantalum with methyl methacrylate (MMA) and diazadiene ligands such as [Cp\*Ta(ฮท -Cy-DAD)(ฮท -MMA)] (structure shown) into effective catalysts for the polymerization of MMA. Polymerization is complete after 10 min at -20ยฐC
