Abstract
Polyaniline base and polyaniline hydrobromide were reacted with bromine in aqueous medium. The content of bromine in the modified polymer increased wi th the amount of bromine introduced into the reaction mixture. The enhanced conductivity of polyaniline base after reaction with bromine was explained by the protonation with hydrobromic acid originating during the brominatio n. FTIR and optical spectra were used to discuss the chemical changes in po lyaniline (PANI). The density of brominated PANI was also determined.
