| Abstract
| - The radical copolymerization reactions of (2-hydroxyethyl methacrylate)−(2-acrylamido-2-methylpropanesulfonic acid), HEMA−AMPS, and (N,N-dimethylacrylamide)−(2-acrylamido-2-methylpropanesulfonic acid), DMAA−AMPS, are exhaustively studied by micellar electrokinetic chromatography(MEKC). Two new MEKC procedures are developed that allow us to follow the monomer consumptiontogether with the copolymer synthesis for the two systems, i.e., HEMA−AMPS and DMAA−AMPS. Theeffects of the conversion and composition on the chemical composition distribution as well as on themolecular weight are analyzed by using this analytical technique. The large possibilities of MEKC forobtaining interesting information about synthesis progress, nature, and composition of the formed ioniccopolymers are demonstrated. Moreover, it is shown that capillary electrophoresis instrumentation canbe used to monitor the electrical conductivity of the reaction product obtained at different copolymerizationstages of the HEMA−AMPS system in order to clarify the polymerization mechanism.
