Abstract
For hydroxypropyl cellulose-ethanol, hydroxyethyl cellulose-water, and cyanoethyl cellulose-DMAA systems, phase diagrams are constructed and the regions of existence of isotropic and anisotropic phases and the dimensions of macromolecules and supramacromolecular particles in a wide composition range are determined through the use of the cloud-point method, polarization microscopy, the turbidityspectrum method, dynamic light-scattering measurements, and a polarization optical apparatus. It is shown that the formation of LC phases with an increase in the polymer concentration is associated with a significant enlargement of supramolecular particles.
