Abstract: Vapor–liquid equilibrium data were determined for five polymer plus toluene systems at isothermal conditions between 60 and 100 oC. 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–Free Volume and the Group Contribution–Flory) were applied to estimate phase behavior of two polymer solutions; good agreement with experimental data was achieved.
Keywords: experimental data; polymer and toluene systems; vapor–liquid equilibrium data
