Abstract: Two surface active ionic monomers(surfmers)[sodium sulfonated lauryl(allyl glyceryl) succinate(ZC-L) and sodium sulfonated lauryl(methacryloyl glyceryl) succinate(ZD-L)] were synthesized and used in the emulsion copolymerization of methyl methacrylate(MMA) and butyl acrylate(BA). The investigation was emphasized particularly on ZC-L for its molecular structure, surface tension behavior and the reactivity for homo and copolymerization. The surface tensions of MMA/BA/Surfmer, MMA/Surfmer and BA/Surfmer copolymer latexes were remarkably higher than that of MMA/BA/sodium dodecyl benzene sulfonate copolymer latex, while similar to or higher than that of MMA/BAemulsifier-free copolymer latex, indicating that the surfmers were covalently bonded on polymer latex particles, and there is only a little remained in the aqueous solution. The ZC-Lcopolymerization reactivity with MMA/BA is better than that of ZD-L.
