Abstract:Â The goal of the present work was to develop a simple lumped model based on monodispersed particle size distribution assumption (all the particles have the same size at a given time) and validate this model against the experimental data of Miller [ Miller, C. M., Ph. D. Dissertation, Lehigh University, U. S. A. (1994)] for styrene emulsion polymerization. The variables considered were the maximum value of the rate of polymerization in Interval II, time at which this maximum occurred, the conversion at which this maximum occurred and the total number of particles formed. The maximum in the reaction rate profile in Interval II of styrene emulsion polymerization was first reported by Varela de la Rosa et al. [Varela de la Rosa, L., Sudol, E. D., El-Aasser, M. S. and Klein, A,. J. Polym Sci. Part A: Polym. Chem., 34, 461, (1996)] and this work provides an explanation of this result.
