摘要
用静态吸收－石英弹簧称重法，测定了２９８．１５Ｋ和３１８．１５Ｋ时１８个聚合物／溶剂系统的汽液平衡．根据汽液平衡数据计算了溶剂的质量分数活度系数ｒ＿Ｗ和Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ相互作用参数Ｘ．
Using the quartz-spring gravimetric mothed, vapor-liquid equilibria of polymer solutions for eighteen different systems at 25 t and 35 t were determined. The mass-fraction activity coefficient of solvents rW and Flory - Huggins interaction parameters X were calculated.
