This paper concerns mathematical modeling and validation of a lab-scale semi-batch emulsion
copolymerization of styrene and butyl acrylate in the presence of n-C12 mercaptan as transfer agent.
The mathematical model is developed by using reaction rate laws available in polymerization
literature. The population balance equations are based on a new approach witch reduces significantly
the number of the equations involved. The model is used to predict the global monomers conversion,
the average molecular weights, the particle size distribution, and the amount of residual monomers. A
subset of the most influential parameters of the model is identified using a parameter estimation
approach by minimizing the errors between the predicted and measured data. Some parameters are
also obtained from literature. The model is then validated in order to be used to compute optimal
profiles of monomers feed-rates which minimize an objective function, subject to a set of tight
operational constraints.
