Abstract: The glass transition temperatures (T_g) of the mixture calcium nitrate—dimethyl sulfoxide—dimethylformamide were determined in dependence on the concentration of calcium nitrate for the constant mole fraction of dimethylformamide in the mixed solvent. It was ascertained that this depen­ dence can be approximated, within the framework of experimental errors, by a linear relation. The dependence of T_g on the composition of the mixed solvent y_DMF calculated from the experimentally determined values of glass transition temperature, can be also described by a linear relation. From experimental data the glass-forming region of the system was constructed.
