摘要：

Chemical oxidative polymerization of aniline in aqueous dispersion stabilized by poly(vinyl alcohol coacetate) in initially neutral and alkaline media was studied by electron absorption spectroscopy and in situ pH measurements. It was shown that polyaniline could be obtained only under conditions when the initial stage of polymerization (formation of oxidized dimer) results in a decrease of pH to values lower than about 2.
