Addition of carbon dioxide to glycidyl methacrylate over polymer-supported quaternary ammonium salt catalysts
In the present study, the synthesis of (2-oxo-1.3-dioxolan-4yl)methyl methacrylate from carbon dioxide and glycidyl methacrylate was investigated using polymer-immobilized quaternary ammonium salt catalysts. The catalysts were prepared by emulsion copolymerization of styrene, divinylbenzene and vinylbenzene chloride (VBC). The influence of partial polymerization time, VBC concentration, structure of the trialkyl amine and counter anion of quaternary salts on the catalytic behavior is discussed. The catalytic activity of the immobilized catalysts was maintained even up to 7 repeated experimental runs.
