| 摘 要： | 文中利用傅里叶红外显微镜和漫反射红外光谱监测聚苯乙烯磺酰氯树脂与乙醇胺在不同温度下的反应程度，对两种方法进行了比较。结果证明漫反射红外光谱是简单有效的方法，而显微红外光谱是研究单个树脂小球之间差异的有效手段。

| Abstract: | 17 FTIR micro transmission spectra of single resin beads of each sample, from polystyrene sulfonyl chloride resin changing to polystyrene sulfonyl amide resin in solid-phase reaction in water at 0 degree C, 20 degrees C, 40 degrees C, 60 degrees C, were recorded. The reaction was monitored by the means of FTIR microspectroscopy and diffuse reflectance spectroscopy upon the products. It was showed that the pressed single bead as a piece of biscuit was able to give higher quality spectrum. In comparison, 8 diffuse reflectance spectra of each sample were also collected. It seems that the diffuse reflectance spectroscopy is a more easy dealing with and effective method to control the whole reaction. However, the microspectroscopy is the first choice to check the difference between resin beads. |
