Abstract
An approach is proposed to understanding the nature of chromaticity of polyacrylonitrile (PAN) solutions thermally treated at 140-degrees-C in dimethylformamide (DMFA) (and films), which is based on the idea of complexes forming between molecules of the basic solvent and the poly mer functional groups modified by the solvent. Manifestation of these structures is registered in electronic spectra as absorption bands wit hin the visible wave band. Stated are the general results of the the e ffect of some basic reactants on the change in PAN structure, includin g heat treatment.
