The synthesis conditions and physico–chemical properties of conductive composites of conjugated polyaminoarenes (PAArs) – polyaniline (PAn), polyorthotoluidine (PoT), polyorthomethoxy-aniline (PoMA) in polymer matrixes of polymethylmethacrylate (PMMA), polyvinyl alcohol (PVA), polybuthylmethacrylate (PBMA), polyacrylic acid (PAA), and polymetacrylic acid (PMA) have been studied. It was found that the dependence of specific conductivity on the conducting polymer content has a percolation character with extremely low "threshold” (2–5% vol.). Based on the temperature dependence of EPR in the temperature interval of 4.2–300 K, a stronger delocalization of charge carries in composites compared with individual polyaminoarenes has been developed. It is established a connection between electrical, mechanical, and thermomechanical properties of polymer–polymer composites studied. On the basis of study optical changes in film composites under gas action the method of obtaining the flexible color indicators for express control of ammonia content in gas environment has been developed.
