The emulsion polymerization of methylmethacrylate(MMA) and styrene(SM) was carried out using initiator, KPS, in the presence of SDS. As the amounts of hydrogen peroxide increased, the monomer conversion and molecular weight decreased, but the particle size increased. In addition, the surface tension of SDS showed CMC in water, resulting in the formation of micelle, but not in hydrogen peroxide. In order to verify the role of hydrogen peroxide in the medium mixture, the same polymerization of MMA was performed in the absence of KPS, and presence and absence of SDS. As a consequence, SDS was important to provide the polymerization site by forming a micelle and hydrogen peroxide was used as an initiator in the absence of KPS. In order to investigate the effect of surfactants, various surfactants, such as anionic, cationic and nonionic ones were used and discussed in terms of the monomer conversion, molecular weight and particle characteristics.
