【Abstract】 The emulsion polymerization of aniline in a system consisted of non-polar or weakly polar solvent, functionized protonic acid and water was carried out using （NH₄）₂S₂O₈ as oxidant. The effects of emulsion polymerization conditions: doping acid, oxidant, reaction time and temperature, water content on the solubility, conductivity and yield of polyaniline were studied. The polyaniline synthesized shows much higher solubility in organic solvents than those synthesized by chemical oxidation polymerization. The PAn-DBSA （dodecylbenzene sulfonic acid） obtained in yield of 80% with conductivity over 1 S/cm.更多还原
