Vapor-Liquid Equilibrium of Copolymer+Solvent Systems: Experimental Data and Thermodynamic Modeling with New UNIFAC Groups

Solubilities of benzene, toluene, and ethylbenzene (BTEX compounds, together with xylene) in poly(ethyl methacrylate) (PEMA) and plasticized PEMA at 298.15 K were measured using a quartz crystal microbalance and are reported in the form of solvent activity versus solvent weight fraction. Two plasticizers, diisononyl cyclohexane-1,2-dicarboxylate (DINCH) and diisooctyl azelate (DIOA), were studied, each at three different concentration levels in the polymer. The presence of a plasticizer increases the solubility of all three compounds. Data were interpreted using a pseudobinary Flory−Huggins model in which the plasticized polymer is considered to be a single pseudocomponent.

Solvent activity versus solvent weight fraction are reported for benzene, dichloromethane and n-propyl acetate in each of two different poly(methyl methacrylate)−polystyrene copolymers and for dichloromethane and n-propyl acetate in polystyrene homopolymer. Results were obtained at 323.15 K for low solvent weight fractions using a quartz crystal balance. A modified Flory−Huggins equation is used to interpret the data.
