Mathematical modeling of polystyrene particle size distribution produced by suspension polymerization

Particle size distribution (PSD) of polystyrene particles produced by suspe nsion polymerization is of fundamental importance in determining suspension stability and product quality attributes. Within a population balance fram ework, a model is proposed for suspension polymerization reactors to descri be the evolution of the PSD. The model includes description of breakage and coalescence rates in terms of reaction kinetics and rheology of the disper sed phase. The model is validated with experimental data of styrene suspens ion polymerization.
