概要 Poly(glycidyl methacrylate) (PGMA) was quant. converted to a polymethacrylate bearing a five-membered cyclic carbonate group (PDOMA) by the polymer reaction with carbon dioxide using alkali metal or quaternary ammonium halide salt as a catalyst. The salts having more Lewis acidic cation and more nucleophilic anion acted as more effective catalysts. Kinetic analyses of the polymer reaction show that the reaction rate can be expressed by the empirical equation: -d[epoxide]/dt = k[epoxide][catalyst]m, where m depends on the Lewis acidity of the catalyst and mol. wt. of the epoxide. The rate of the reaction is independent of the pressure of carbon dioxide. The presence of an arom. group in the structure of the polymer could retard the reaction with carbon dioxide.
