摘要
建立了一套用差压法测定聚合物溶液汽液相平衡数据的实验装置．用乙醇纯溶剂及聚苯乙烯／甲苯溶液作为标准体系，对实验装置进行了校核．在温度范围为303.15K～333.15K及常压下，用本实验装置测定了4种聚合物（聚苯乙烯，聚氯乙烯，聚乙二醇，聚甲基丙烯酸甲酯）+6种溶剂（间-二甲苯，水，氯仿，乙酸乙酯，2-丁酮，环己酮）的14个二元体系汽液平衡数据，用简化空穴理论状态方程对实验数据进行了关联．
A differential pressure apparatus was established for the measurements of vapor-liquid equilibria（VLE）for polymer－solvent solutions，Pure ethanol and polystyrene-toluene solution were used for the test of the apparatus.Fifteen sets of VLE data were measured in a temperature range from 303.15K～ 333.15K for the binary systems:polystyrene+ethyl acetate,polystyrene+m-xylene,polystyrene+cyclohexanone,poly（vinyl chloride）（PVC）+cyclohexanone,PVC+2-butanone,Poly（methyl methacrylate）（PMMA）+ chloroform,PMMA+cyclohexanone,poly(ethylene glycol)（PEG）+water,PEG+chloroform.The simplified hole theory equation of state proposed by this group was used to correlate accurately the data measured.
