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°C, 20°C, 40°C, 60°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 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.
