    Study on Vapor-liquid Equilibria for Acetone-PMMA and Ethyl Acetate-PMMA Systems

      摘要
    • 摘要: 采用石英弹簧重量法，对三种不同相对分子质量的ＰＭＭＡ单分散样品，测定了３５℃下丙酮－ＰＭＭＡ、乙酸乙酯－ＰＭＭＡ系统的汽液平衡数据。分析了Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ相互作用参数χ与溶液组成及样品相对分子质量的关系。用Ｅｌｂｒｏ－ＦＶ模型预测了溶剂活度系数，并与实验结果进行了比较。

       

      Abstract: The vapor-liquid equilibria(VLE)of polymer solutions for acetone-polymethyl methacrylate(PMMA)and ethyl acetate-PMMA systems at 308.15K were determined by using a multicell vapor-adsorption quartz-spring apparatus,Flory-Huggins interaction parameters were calculated.Elbro model was applied to predict the VLE of solvent-polymer systems,and the predicted results were compared with the experimental results.
