Description
Summary:This article explores the possibility to determine thermokinetic parameters with a calorimetric method using a reaction calorimeter RC1–RTCal. This method was illustrated with a radical solution polymerization. In opposition to classical polymerization kinetic studies (PLP, DSC), operating conditions are near industrial processes and kinetic parameters are estimated up to high reaction extent. The method consists in comparing thermal power profiles measured during experiments with profiles calculated by means of a model. A minimization method based on a genetic algorithm estimates individual kinetic parameters of the three steps of the model (initiation, propagation, termination). Kinetic parameters values are compared to literature.
