摘要: 将石英晶体微平衡法(QCM)用于气体在聚合物中溶解度的测定, 实测的CO2在尼龙66、天然橡胶和聚氯乙烯中的溶解度与文献值符合较好.测定了CO2在聚苯乙烯、聚甲基丙烯酸甲酯和聚甲基丙烯酸正丁酯3种均聚物及苯乙烯-甲基丙烯酸甲酯共聚物、苯乙烯-丁二烯-苯乙烯共聚物、甲基丙烯酸正丁酯-甲基丙烯酸二甲基氨基乙酯共聚物和甲基丙烯酸正丁酯-丙烯酸全氟烷基乙基酯共聚物等嵌段共聚物中的溶解度, 并用链状流体状态方程对实验数据进行了关联,结果令人满意.

Abstract: A new apparatus based on quartz crystal microbalance has been established to measure the solubilities of gas in polymer. The measured solubilities of CO2 in Nylon 66,nature rubber and polyvinyl chloride are in good agreement with literature data. The solubilities of CO2 in 3 homopolymers including polystyrene, poly(methyl methacrylate)and poly(n-butyl methacrylate), and in 8 block copolymers including poly(styrene-co-methyl methacrylate), poly(styrene-co-butadiene-co-styrene), poly(n-butyl methacrylate-co-N,N-dimethylaminoethyl methacrylate), poly(n-butyl methacrylate-co-perfluoroalkylethyl acrylate) are measured. The equation of state for chain fluids developed by Peng et al.is used to correlate the experimental data.Satisfactory results are obtained.
