The reaction kinetics of model thiol-epoxy polymer networks (TEPNs) was visualized by tracking pH variation occurred during cross-linking reaction. Color transition of TEPNs was monitored in real-time and the result was correlated with other characterization techniques such as Fourier transform infrared (FT-IR) spectroscopy, isothermal differential scanning calorimetry (DSC), and oscillational rheology measurements. Influence of glass transition temperature (Tg) on reaction kinetics of TEPNs during the low temperature cross-linking reaction was investigated by employing various TEPNs having different functionality of cross-linkers.
