PRODUCTION, PHYSICOCHEMICAL AND SPECTRAL-LUMINESCENCE PROPERTIES OF ANTHRAQUINONE-CONTAINING POLYAMIDES

Mono-, di-, and tri-staged methods of copolycondensation of the mixture of m-phenylenediamine and diaminoanthraquinones with isophthaloylchloride have been studied. A fraction of bound chromophore diamine and molecular mass of copolyamides formed have been shown to be defined by both basicity of initial diaminoanthraquinones and the copolycondensation method chosen. From the studies of physicomechanical, thermomechanical and spectral-luminescent characteristics of structural colored copolyamides the conclusion has been drawn that introduction of chromophore groups into polyamide chain in concentrations of 0.5-1.0% does not practically affect its submolecular structure. Absorption and luminescence spectra have been investigated of solutions and films of polymethaphenyleneisophthalamide with fragments of diaminoanthraquinones in the chain, as well as those of aminobenzoylamine derivatives and dibenzoylamine derivatives simulating chromophore links of polymer chain. Character of alternation of chromophore groups in macromolecules has been established from comparative analysis of spectral and luminescence properties of the above structures.
