Abstract : The Maximum Principle was applied to determine temperature and initiator addition policies that minimize reaction times for chain addition polymerizations in batch reactors. The gel efffect was considered. The optimal policies were found to be a rising temperature and a constant initiator concentration such that k(eff) for monomer conversion is constant. Under a strong 'dead end' effect, the optimal policy results in a significant reduction in the polymerization reaction time. Numerical examples for the polymerization of styrene and methyl methacrylate are presented. (Author)
