A multiobjective dynamic optimization problem using conflicting performance objectives in polymerization systems is formulated. We use the dynamic one‐dimensional mathematical model of a methyl‐methacrylate cell cast reactor featuring monomer conversion and molecular weight distribution as the conflicting objectives. The aim is to compute the whole set of trade‐off solutions comparing the performance of three well known procedures for addressing the solution of multiobjective optimization (MO) problems: normal boundary intersection, weighted sum, and epsilon‐constraint. Using the air temperature profile as the manipulated variable, we demonstrate the dynamic optimal solutions obtained using the best trade‐off solution from each one of the MO techniques.
