Proton nuclear magnetic resonance (1H NMR) spectroscopy experiments were carried out for a commercial epoxy resin system in [2H6]DMSO solution and in bulk. Good agreement was obtained between the secondary rate constants found for the epoxide polyetherification reaction when monitored by Fourier-transform infrared (FTIR) or 1H NMR spectroscopy in the bulk over the range of temperatures studied. This highlights the usefulness of the high temperature bulk NMR technique in kinetic studies of polymerization.
