Kinetics modeling of the reaction for an Epoxy/PMMA/MMT ternary system

Résumé

The effect of thermoplastic PMMA and clay Cloisite 30B addition on the cure kinetics of an epoxy/amine thermosetting system was investigated using differential scanning calorimetry (DSC) and modelled using a single kinetic model. For obtaining a good agreement between the experimental results and theoretical modeling, it was necessary to separate the ternary system in two formulations: matrix/PMMA and matrix/clay systems. It appeared that the addition of PMMA delays the reaction up to the phase separation phenomenon due to a dilution effect of the reactive species. In opposition, the presence of clays accelerates the reaction (probably due to a catalytic effect of some metals ions introduced with the clay) but it has no sensitive effect on the cloud point conversion in the presence of PMMA. The modeling results are in good agreement with those experimentally obtained
