Abstract

The structure, intra- and intermolecular interactions, and conformations of macromolecules in cellulose diacetate films under the conditions of formation of the liquid crystal state in the course of nitromethane vapor sorption were studied by Fourier IR spectroscopy and polarization microscopy. The number of intramolecular hydrogen bonds stabilizing the rigid helical conformation of the macromolecules is preserved in the process. The anisotropic structure of cellulose diacetate films is also preserved after desorption of the sorbed solvent vapor.
