ABSTRACT

The kinetics of resol resin cross-linking was investigated by a single-heating-rate DSC method. A simple kinetic model was developed, which predicts the behavior in the industrial impregnation process of laminate manufacture. It was found that the curing rate can be well described by a pseudo first-order kinetic model with apparent activation energy of 87.3 kJ/mol. The kinetic model was verified by comparing calculated and experimental conversions obtained in the run at the production line.
