A recoverable versatile photo-polymerization initiator catalyst
  A photo-polymerization initiator based on an imidazolium and an oxometalate, viz., (BMIm)2(DMIm) PW12O40 (where, BMIm = 1-butyl-3-methylimizodium, DMIm = 3,3'-Dimethyl-1,1'-Diimidazolium) is reported. It polymerizes several industrially important monomers and is recoverable hence can be reused. The Mn and PDI are controlled and a reaction pathway is proposed.
