Etude et modélisation de la stabilité thermique et des propriétés des polyamides au cours du rotomoulage

Abstract : The rotational molding is a technique for implementation ofthermoplastic polymers. This process is subject of several studies in recent years. The purpose of our work is the thermal and chemical modeling of this process, taking into account the phase changes, in particular the crystallization and melting. These phasechanges were digitally processed for each polymer layer used in this study, using a method known as enthalpic then by another method derived from the crystallization kinetics. This method has been modified and adapted to our work by taking a coupling of two concepts: the first approach reflects the release of heat during processing of crystallinity; the second concept is the chemical modeling of the thermal degradation ofpolyamides.
