✦ Synopsis
In suspension polymerisation processes, the principal aim is the formation of as uniform a suspension as possible of monomer droplets in an aqueous phase and the prevention of coalescence of these droplets during reaction, as this controls the size distribution of final polymer particles. In order to understand what influences drop size in a reactor, we have modelled drop breakage and coalescence rates using discretised population balance equations. The model reactor chosen in our work is the novel oscillatory baffled reactor (OBR). In this article, we report our recent investigation on the reliability of the breakage and coalescence rates evaluated using the model and our thoughts for the way forward.
