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。

The infinite dilution activity coefficients of 16 solvents in the range of 34 3 ~ 4 33K in polybutylmethacrylate (PBMA) were determined by reversed-phase gas chromatography. The effect of experiment was also studied by the molecular thermodynamic model of polymer solution The results were correlated and the results were satisfactory.
