Abstract

Poly(2-bromoaniline) was prepared by oxidation of 2-bromoaniline with ammonium peroxydisulfate in the presence of hydrochloric acid. The conductivity of the poly(2-bromoaniline) hydrochloride so produced was 10<sup>-6</sup> S cm<sup>-1</sup>, its density at 20 °C 1.78 g cm<sup>-3</sup> and weight-average molar mass 18 500 g mol<sup>-1</sup>. The degree of protonation was estimated as being a half of that of polyaniline. The structure of poly(2-bromoaniline) is discussed on the basis of FTIR spectra. Colloidal dispersions were produced when the polymerization had been carried out in the presence of a particulate or polymeric stabilizer, <i>viz.</i> colloidal silica, poly(vinyl alcohol), poly(<i>N</i>-vinylpyrrolidone) or (hydroxypropyl)cellulose. The UV-VIS spectra of colloidal dispersions are used to discuss the transition between the protonated and base forms. <p>
