Abstract: On the basis of population balance a mathematical model is developed to describe the
formation of polymer partlcle in styrene suspension polymerization. The characteristics of
coalescence and breakage of droplets and the gel effect are analyzed in particular.
Parameters of the models are esthnztted by experimental. on reaction conversion and
particle size distributlon. The results show that the model is suitable for predicting
polymerization processes.

Key words: population balance model, styrene, suspension polymerization, particle size distribution
