Efficient Gas−Solid Phase Reaction of Atmospheric Carbon Dioxide into Copolymers with Pendent Oxirane Groups: Effect of Comonomer Component and Catalyst on Incorporation Behavior

The appropriate choice of catalysts and comonomers improved the selectivity of the gas−solid-phase reaction of carbon dioxide into copolymers from glycidyl methacrylate (GMA), which transforms the pendent oxirane moieties to cyclic carbonate moieties. Benzyltributylammonium chloride (BnBu 3 NCl) exhibited good and selective catalytic behavior owing to its appropriate mobility in the copolymer film and moderate catalytic activity. n -Butyl methacrylate proved to be an effective comonomer, resulting in higher incorporation efficiency and better selectivity by preventing the cross-linking reaction, allowing one to obtain soluble polymers bearing cyclic carbonate structure.
