用石英晶体微天平在298.15 K下测定了苯、甲苯和三苯甲烷在环己烷-1，2-二羧酸二异壬酯和壬二酸二异辛酯增塑聚甲基丙烯酸乙酯和在硬脂酸正丁酯增塑聚苯乙烯中的溶解度。薄膜中苯、甲苯和甲苯的测量浓度在0至约1.0重量%的范围内，并用于估计增塑聚合物中这些溶剂的无限稀释活度系数。
Solubilities of benzene, toluene, and ethylbenzene in plasticizing poly(ethyl methacrylate) with diisononyl cyclo-hexane-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.
