Radical dispersion polymerization of glycidyl methacrylate accompanied by CO2 fixation yielded particles of polymers bearing cyclic carbonate and epoxide moieties in the presence of polymeric dispersion stabilizers. Cellulose acetate successfully stabilized the dispersion, whereas poly(N-vinylpyrrolidone) did not. Spherical particles with diameters of 1-10 mu m could be prepared under the optimized conditions. The epoxide moieties in the particle were hydrolyzed selectively keeping the shapes of the particles. (C) 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 48: 5382-5390, 2010
