Polymer Composition Control in Emulsion Co- and Terpolymerizations

Abstract : A new strategy for composition control in emulsion copolymerization and terpolymerization processes, based on the use of nonlinear estimation and control techniques, is presented in the current work. The strategy uses the estimation of the concentration of monomers in the reactor, and the manipulated variables used for the composition control are the flow rates of the most reactive monomers, calculated in such a way as to account for the reaction rate, thereby allowing us to anticipate changes in the polymer composition. The controllers are experimentally validated for several composition set points and systems. It was found that the controllers maintain the composition at the desired value even for monomers with a wide difference in their reactivity ratios.
