摘　　要：Poly-ortho-methylanilines (POT) in three states fully oxidized, fully reduced and oxidized in varying degrees were synthesized by the reaction of common POT (C-POT) having nearly equal amounts of benzenediamine and quinonediimine units with iodine or phenylhydrazine, and the resulting polymers were characterized by IR,^(13)C-NMR, SEM and elemental analysis. The results showed that the quinonediimine unit in C-POT could be reduced by phenylhydrazine to the benzenediamine unit,forming the polymer with low OD (oxidation degree) or in a fully reduced state and that iodine-oxidation resulted in the increase of quinonediimine unit and decrease of benzenediamine unit. The solubility and flexibility of the formed polymers depend strongly on the amount of quinonediimine unit in it. It is necessary to reduce the content of quinonediimine structure unit in order to improve the solubility of aniline-class polymers.Poly-ortho-methylanilines （POT） in three states fully oxidized, fully reduced and oxidized in varying degrees were synthesized by the reaction of common POT （C-POT） having nearly equal amounts of benzenediamine and quinonediimine units with iodine or phenylhydrazine, and the resulting polymers were characterized by IR,¹³C-NMR, SEM and elemental analysis.
