Аннотация:IR and Auger electron spectroscopy and spectroscopy of characteristic energy losses of electrons have been used to study the reaction of dehydrohalogenation of polyvinylidene halides on exposure to an alcoholic solution of alkali in presence of THF. It is shown that on chemical dehydrohalogenation of the polyvinylidene halides the cumulene form of carbyne appears. The mechanism of the reaction is discussed. The scheme of the formation of the cumulene structure and the triple carbon-carbon bonds is proposed. It is whown that in the IR spectra of carbyne absorption of the cumulated double bonds is manifest in the region 1600 cm−1.
