Abstract	A recoverable photo-polymerization catalyst based on an imidazolium and a polyoxometalate, viz., $(BMIm)_{2}(DMIm)PW_{12}O_{40}$ (where, BMIm = 1-butyl-3-methylimidazolium, DMIm = 3,3′-dimethyl-1,1′-diimidazolium) is reported. It catalyzes photo- polymerization of several industrially important monomers like styrene , methyl methacrylate , butyl methacrylate and vinyl acetate . The catalyst is recoverable and hence can be reused. The molecular weight and polydispersity index can be controlled reasonably and a reaction pathway is proposed. The synthesis of this novel catalyst is reported and the catalyst has been characterized using standard techniques such as single crystal X-ray diffraction studies, cyclic voltammetry and various spectroscopic methods such as Fourier transform infrared spectroscopy , $^{1}H$ NMR spectroscopy , EPR spectroscopy and UV-Vis spectroscopy . DFT calculations have been used to explain the catalyst's photo-chemical activity.
