Hydrodynamic and sorption behavior of a number of cellulose acetates in diluted non-aqueous solutions were studied by viscosimetry and reversed gas chromatography techniques, respectively. Effect of the chemical nature of low-molecular organic substances on swelling of the molecular coils of the said polymers as well as the coil-to-rigid-rod conformational tran-sition of the macromolecules was revealed. Thermodynamic compatibility of the polymers with non-aqueous solvents at infinite dilution was determined.

Keywords: cellulose esters, hydrodynamic and sorption characteristics
