Vapor–liquid equilibrium data were determined for five polymer + toluene systems at isothermal conditions between 333.15 and 373.15 K. Polymers comprise copolymers and terpolymers of octadecyl acrylate, acrylic acid, styrene, and 1-vinyl-2-pyrrolidone because of their practical importance as flow improvers for crude oil and/or derivatives. All-glass micro-ebulliometer with circulation of liquid phase was used for measurement of total pressure over polymer + toluene mixtures. Two predictive group contribution models (the Entropic-FV and the GC-Flory) were applied to estimate phase behavior of two polymer solutions; good agreement with experimental data was achieved.
