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.

聚甲基丙烯酸乙酯和增塑聚甲基丙烯酸乙酯在石英晶体微量天平上于298.15 K吸附苯，甲苯和乙苯

使用石英晶体微量天平测量了苯，甲苯和乙苯（BTEX化合物以及二甲苯）在聚甲基丙烯酸乙酯（PEMA）和增塑的PEMA中在298.15 K时的溶解度，并以溶剂活性相对于溶剂重量的形式记录分数。研究了两种增塑剂，二异壬基环己烷-1，2-二羧酸酯（DINCH）和壬二酸二异辛酯（DIOA），每种增塑剂在聚合物中的浓度分别为三种。增塑剂的存在增加了所有三种化合物的溶解度。使用伪二进制Flory-Huggins模型解释数据，在该模型中，增塑的聚合物被视为单个伪组分。
