Preparation of charged polystyrene microlatexes by emulsion polymerization induced by gamma rays

摘要

Ionic polymerizable surfactants MOBS and MOTB were synthesized and used as emulsifier to synthesize monodisperse polystyrene microlatexes by emulsion polymerization induced by gamma rays. Transmission electron microscopy and X-ray fluorescence were used to characterize the prepared polystyrene. The results show that ionic polymerizable surfactants are effective in the preparation of monodisperse polystyrene microlatexes, and that emulsion polymerization induced by gamma rays has advantages over initiator-induced emulsion polymerization. A possible nucleation stage was suggested and the kinetics of the process was also analyzed.
