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.

聚甲基丙烯酸甲酯/聚苯乙烯共聚物在石英晶体天平上于323.15 K吸附苯，二氯甲烷和乙酸正丙酯

报告了两种不同聚（甲基丙烯酸甲酯）-聚苯乙烯共聚物中苯，二氯甲烷和乙酸正丙酯的溶剂活性与溶剂重量分数的关系，以及聚苯乙烯均聚物中二氯甲烷和乙酸正丙酯的溶剂活性与溶剂重量分数的关系。使用石英晶体天平在323.15 K下获得了低溶剂重量分数的结果。修改后的Flory-Huggins方程用于解释数据。
