The byproducts formed in chem. or electrochem. oxidative polymerisation of aniline in acid medium were separated and characterized by IR, 1H-NMR, and elemental anal. The main byproducts were 2,5-dianilino-p-benzoquinone and its derivatives and the amount of byproducts increased with increasing concentration of oxidants in the polymerisation A possible forming process of the byproducts was proposed.
