The application of trinuclear nickel clusters as air-stable catalysts for the production of specific polymer architectures (e.g. syndiotactic polystyrene: sPS, or syndiotactic polymethylmethacrylate), from polar and apolar monomers under energy efficient (i.e., room temperature: RT) conditions using minimal amounts of aluminium- based co-catalysts (e.g., MAO), is described. This novel process represents the first air- stable Ni-based system for the synthesis of stereo-regular vinyl polymers and hence is a "greener" and more cost-effective catalyst technology for the production of such industrially useful polymers.
