The processes of electrosynthesis, electrochemical behaviour and electrochromic properties of polyaminoarenes of different nature and position of substitutents in benzene ring - poly-o-(m)- aminophenols, poly-o-toluidine, poly-o-methoxyaniline and polyaniline have been studied in aqueous acid electrolytes. It has been shown that particularities of electrochemical and electrochromic transitions in polyaminoarene films obtained on SnO2 electrodes are defined by the charge transport parameters depending on the molecular structure of the polymers, type of electrolyte anion and associated with an ion-diffusion phenomena on the polymer-solution interface.
