“…Zhang et al [25] have found that the particle size of BA/MMA/AA copolymer was decreased from 145 to 122 nm when the surfactant concentration increased from 1.5% to 4%. Chanra et al [26] calculated that the particle size for poly-(St-co-BA-co-MMA) decreased from 156 to 80 nm as the SDS concentration increased from 0.50 to 4.00 %.…”

“…They indicated that when SLS and p-octyl polyethylene glycol phenyl ether (OP) mixed surfactants were added, at the amount of 3%, and a ratio of SLS/OP of 4/6, the latex showed lower coagulum. Chanra et al [26] showed that monomer conversion rate (> 99%) increased with the increasing amount of watersoluble surfactant SDS from 2.0 to 4.0 wt%, but particle size increased from 80 to 102 nm [26]. Surfactants behave as "solubilizing" non-polar substances like organic monomers above their CMC.…”

In this study, the concentration effect of sodium lauryl sulfate (SLS) as a surfactant in the synthesis of styrene/acrylic acid/butyl acrylate copolymer (SAC) latex particles via seeded emulsion polymerization technique was investigated. Scanning electron microscopy (SEM), minimum film-forming temperature (MFFT), differential scanning calorimetry (DSC), dynamic light scattering (DLS), and thermal gravimetric analysis (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.
