The effects of temperature, concentrations of initiator (KPS) and emulsifier (SDS) on emulsion polymerization of 2,5 dimethoxyaniline (DMAn) were investigated. The polymer PDMAn with number average molecualr weight of 1.22×10⁴ was obtained in the conditions, [monomer]=6.0×10^-3 mol/L, [SDS]≥5.0×10^-2 mol/L, [KPS]=3.5×10^-3 mol/L, 85℃, for 2.0 h. ¹H NMR, FTIR and TEM techniques were used in structure characterization, the results showed that the polymer was produced by para polymerization and the ratio of benzoid to quinoid units was 3:1 in its macromolecular chain.
