Abstract: The glass transition temperatures (7^) of the mixture calcium nitrate—water—dimethylformamide were determined in dependence on the con­ tent of calcium nitrate for the constant mole fraction of dimethylformamide in the mixed solvent. It was ascertained that this dependence can be ap-. proximated, in the framework of experimental errors, by a linear relation. On the basis of experimentally ascertained values of the glass transition temperature the dependence of Tg on the composition of the mixed solvent (y_DMF) was calculated. Maxima were ascertained on the curve representing this dependence, and the extents of the glass-forming regions were deter­ mined.
