摘　　要：采用气相色谱法分析聚甲基丙烯酸甲酯(PMMA)中甲基丙烯酸甲酯(MMA)、甲苯的含量。以丙酮为溶剂,外标法为定量分析方法。溶剂与待测组分在HP-1毛细柱上获得较好的分离。MMA的线性相关系数R=0.9990、平均回收率为97%;甲苯的线性相关系数R=0.9992、平均回收率为101%;精密度实验峰面积相对标准偏差(RSD)≤5.0%准偏差。该分析方法简便、准确,适合PMMA中试实验。The contents of methyl methacrylate(MMA)and toluene in polymethylmethacrylate(PMMA)were analyzed by gas chromatography.Acetone was used as solvent and external standard method as quantitative analysis method.The solvent and the components to be tested were well separated on HP-1 capillary column.The linear correlation coefficient(R)of MMA is 0.9990 and the average recovery is 97%.The linear correlation coefficient(R)of toluene is 0.9992 and the average recovery is 101%.The relative standard deviation(RSD)of peak area in precision experiment is≤5%.The analytical method is simple and accurate.It is suitable for PMMA pilot test.
