Free radical solution polymerization of styrene in two stage polymerization process hasbeen studied using a binary mixture of symmetrical bifunctional initiators. The continuousreactor system was composed of two reactor units; a prepolymerization reactor (e.g. stirredtank reactors) and a filled tubular reactor packed with static mixers. When the stirred tankreactor was used as a prepolymerizer, a feed stream to the filled tubular reactor was moreviscous than the monomer/solvent mixture. It was of interest to investigate how theperformance of the filled tubular reactor has been investigated by the feed of viscousprepolymer solution. A dynamic model of the continuous two stage polymerization processwas presented by experimental data and model simulation. A reasonably good agreementbetween the model and the experimental data was obtained without using any adjustableparameters. The experimental results of the two stage polymerization were compared with theresults without prepolymerization reactor. It was found that the addition of aprepolymerization reactor has almost no effect on the performance of the filled tubular reactor.
