An experimental set‐up for in situ real‐time monitoring of chemical reactions by remote fiber optic near‐infrared spectroscopy was assembled in our laboratory and is described in this communication. A series of epoxy/amine formulations, nonpolymer‐forming, and polymerforming alike, were prepared and their reaction kinetics investigated. Accurate and reproducible spectra were generated, the characteristic near‐infrared peaks assigned, and the reaction kinetics evaluated by monitoring the rates of disappearance and/or appearance of the characteristic peaks. The effect of the chemical structure and functionality of the components were pointed out and a method suggested to correlate the spectral information with the chemophysical changes in multifunctional formulations.
