Abstract: The emulsion polymerization of aniline in three-phase system of xylene-functionalized protonic acid-waterwas carried out using (NH4)2S2O4 as oxidant. The influences of water phase concentration on the viscosity, conductivity, transmittance of polyaniline(PAN) latex and its powders were studied. The results show that the properties of PAN prepared through the emulsion polymerization are influenced by the amount of water used in the polymerization. The morphology of PAN varieswith thewater phase concentration used in the polymerization, which may result in the change of properties of PAN latex and its powders. When the volume fraction ofwater (φ) is about 20%-30%, the prepared PANpowder has higher conductivity, and the PAN la-tex has appropriate viscosity and particle size. The consumption of xylene was reduced at high φ value.
