Modélisation, expérimentation et optimisation multicritère d'un procédé de copolymérisation en émulsion en présence d'un agent de transfert de chaîne

Abstract : The objective of this study is to develop a methodology in order to determine and implement the optimal operating conditions of the emulsion fed-batch copolymerization process of styrene and butyl acrylate in the presence of a chain transfer agent. It particularly aims to optimize the production and the physico-chemical characteristics of latex particles with targeted end-use properties. After an experimental study, the process model has been developed taking into account the particular effect of the chain transfer agent on the polymerization kinetic and highlights the population balance. Thanks to an estimability analysis approach, 21 parameters among the 49 parameters of the model have been selected whose values have been identified by using a genetic algorithm. The mathematical model validated in both batch and fed-batch modes was then exploited for the multicriteria optimization of the process oriented towards the maximization of the production of latex particles having a core-shell type morphology with a given glass transition temperature profile. The Pareto's front solutions were obtained thanks to an evolutionary algorithm developed and tested for this purpose. The best alternative obtained by a decision-making aid tool was finally experimentally implemented and successfully compared with the predictions of the mathematical model
