ABSTRACT
The oxidative copolymerization of aniline with p-phenylenediamine in an acetic acid medium has been investigated for the first time. It has been determined that as a result of copolymerization; a polymer having a structure analogous to the polyaniline called emeraldine is formed. The obtained copolymer doped with 3N hydrochloric acid has an electrical conductivity five times higher than that of polyaniline prepared by the usual method. Aniline polymerization proceeds more slowly at 273 K under the same copolymerization conditions and the obtained polymer has low conductivity. However, in a mixture of acetic acid-methanol, the reaction proceeds faster and the obtained polymer has conductivity almost equal to that of emeraldine. It has been observed that the conductivity of polymers doped with formic acid is lower than that of polymers obtained by doping with hydrochloric acid by 2 orders of magnitude.
