Study of the curing process of an epoxy resin by FTIR spectroscopy

The curing process of an epoxy resin of glycidic polyether by Fourier transform infrared spectroscopy has been studied. The influence of the hardener/resin ratio, temperature, and curing time have been determined. This article discusses which bands of the infrared spectrum and what relation of their absorbances are most convenient to monitor the resin-curing process.
