摘要
用反相气相色谱方法测定了 1 6种溶剂在聚甲基丙烯酸丁酯 ( PBMA)中 34 3～ 4 33K范围内的无限稀释活度系数 ,并用周浩等的高分子溶液分子热力学模型对实验结果进行了关联 ,结果令人满意。
Inverse gas chromatography (IGC) method has been used to measure the infinite diluted activity coefficient of 16 solvents including aromatics, halogenated hydrocarbons, alcohols and esters in poly(butyl methacrylate)(PBMA) at temperatures from 343K to 433K.The molecular thermodynamic models of polymer solutions presented by Zhou et al. have been used to correlate the experimental infinite diluted activity coefficients of solvents in PBMA.
