Abstract :In this study, the concentration effect of sodium lauryl sulfate insert ignore into journalissuearticles values(SLS); as a surfactant in the synthesis of styrene/acrylic acid/butyl acrylate copolymer insert ignore into journalissuearticles values(SAC); latex particles via seeded emulsion polymerization technique was investigated. Scanning electron microscopy insert ignore into journalissuearticles values(SEM);, minimum film-forming temperature insert ignore into journalissuearticles values(MFFT);, differential scanning calorimetry insert ignore into journalissuearticles values(DSC);, dynamic light scattering insert ignore into journalissuearticles values(DLS);, and thermal gravimetric analysis insert ignore into journalissuearticles values(TGA); techniques were used to explain the change on physicochemical properties and morphology. The main goal is to determine an optimal surfactant concentration to obtain latexes with low MFFT. DLS studies showed that the particle size decreases 118.30 to 75.18 nm with the increase of SLS concentration. MFFT of latexes decreased with increasing SLS concentration. From the TGA curves, it was found that all the SAC latex particles exhibit a three-step decomposition process. The observed single Tg values for SAC particles showed that the latexes were prepared successfully.
