New experimental liquid-liquid-phase equilibrium data are reported for aqueous systems containing poly(vinyl pyrrolidone)-of different molecular mass-and sodium sulfate at (298 and 338) K together with parameters for a semiempirical model for the excess Gibbs energy which is used to describe the experimental data.
