    A novel polymerizable surfactant (surfmer) based on nonyl phenol ethoxylate backbone and maleic anhydride was synthesized. The chemical structure of the surfmer was characterized by C-13, H-1 nuclear magnetic resonance, and surface tension analyses. The surfmer was used in emulsion system of methyl methacrylate/butyl acrylate copolymer at different concentrations to explore its stabilization efficiency using seed emulsion polymerization technique. The result of thermogravimetric analysis showed that the incorporation of the surfmer retarded the decomposing of the polymer chain. The stability of the emulsion was enhanced by adding the surfmer, but the glass transition of the film was decreased dramatically. [GRAPHICS] .
