Continuous emulsion polymerization of vinyl acetate. Part III: Detection of reactor performance by turbidity‐spectra and liquid exclusion chromatography

Abstract

Abstract Herein is reported an experimental evaluation of turbidity‐spectra and of liquid exclusion chromatography (LEC) for the online and offline monitoring of polymer particle size during the continuous emulsion polymerization of vinyl acetate. It is shown that these analytical techniques satisfactorily follow the change of particle size for reactor operation under conditions of sustained oscillations.
