摘要：

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 degreesC, 20 degreesC, 40 degreesC ,60 degreesC, were recorded. The reaction was monitored by the means of FTIR microspectroscopy and diffuse reflectance spectrocopy 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 spectrscopy 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.
