Abstract
The thermodynamics of the plasticization of cellulose nitrate by diethylene glycol and triethylene glycol nitrates was studied. The measurements of the saturated vapor pressure of the plasticizing agents over the plasticized polymer allowed one to calculate the isotherms of the chemical potentials of the plasticizing agents, as well as the partial enthalpy and entropy of mixing. The results were evaluated from the standpoint of the theory developed for the solutions of semirigid macromolecules with account for solvation effects. The conditions of phase equilibrium were determined, and the phase diagrams were constructed. A hypothesis concerning the LC nature of cellulose nitrates plasticized with nitroesters was advanced.
