Аннотация:Polyaniline (PANI) was synthesized by chemical oxidation of aniline in the presence of mixtures
of water-soluble poly(sulfonic acids) of different nature. Under these conditions, the use of polyacid
templates leads to the formation of interpolymer complexes of PANI and polyacid mixtures. The
obtained PANI complexes were characterized by UV, visible, near IR, and Fourier transform infrared
spectroscopy. It was shown that the rigidity of the polyacid backbone and the composition of a
polyacid mixture affect the electronic structure of PANI complexes and the duration of the induction
period of aniline oxidation. Domination of the more rigid-backbone template in the synthesis of
PANI complexes with mixtures of the rigid- and flexible-backbone polyacids was observed. According
to the viscometry and FTIR spectroscopic data, the reason of the domination is the existence of
the intermolecular interaction between the polyacids in the mixture. In this case, duration of the
induction period of aniline oxidation was between these values for pure polyacids.
