This invention provides a method for synthesizing polyaniline derivatives from the reaction of polyanilines with 2-sulfobenzoic anhydrides. The structure of polyaniline derivatives are composed of the following repeating units: wherein X+Y+2Z ≤ 1.0, x ≥ 0.1; n is an integer from 1 to 4; M is H, Na, K or NH4; R1 R2, R3 and R4 are independently selected from the group consisting of -H, -R0, -F, -CI, -Br, -OR0, -COR0, -OCOR0, -NHCOR0, -NO2, -COOR0, -CN and -COOH; Q means a group represented by the formula: -H, -R0, -F, -Cl, -Br, -OR0, -COR0, -OCOR0, -NHCOR0, -NO2, -COOR0, -CN, -COOH, wherein R0 denote an alkyl group with the carbon number from 1 to 4. The polyaniline derivatives, with the conductivity up to 10-3 to 10-4 S/cm, are water soluble and self-acid-doped.
