Etude et modélisation du procédé d'élaboration de résines acryliques dures par terpolymérisation du système styrène, [alpha]-méthylstyrène, acide acrylique en réacteur tubulaire

Abstract : The hard acrylic resins synthesis process has been studied. The chemical reaction, initiated by an organic peroxide, is a terpolymerization between styrene, [alpha]-methylstyrene and acrylic acid. The mass or solution polymerization is carried out in a tubular reactor at high temperature (between 200 °C and 260 °C) and with a pressure of 20 bar. Residence times in the reactor are smaller than 5 minutes. The first step of this work has been to define an experimental strategy in order to study the influence of the major operating parameters (residence time and oil temperature). The experimental results will also be used in the elaboration of a tendency model, which objective is to predict the conversions of each monomer and the product properties. The unknown parameters of this model have been identified using the genetic algorithm technique. Then, this model has been adapted for the simulation of the hard acrylic resin industrial production facility.
