Sorption of Benzene, Toluene, and Ethylbenzene at Low Concentrations by Plasticized Poly(ethyl methacrylate) and Polystyrene Polymers Using a Quartz Crystal Microbalance at 298.15 K

Abstract

Solubilities of benzene, toluene, and ethylbenzene in plasticizing poly(ethyl methacrylate) with diisononyl cyclohexane-1,2-dicarboxylate and diisooctyl azelate and in polystyrene with n-butyl stearate are reported in the form of activity versus weight fraction data, measured using a quartz crystal microbalance at 298.15 K. Measured concentrations of benzene, toluene, and ethylbenzene in the films are in the range of 0 to approximately 1.0 weight percent and are used to estimate infinite dilution activity coefficients of these solvents in the plasticized polymers.
