Fouling in Emulsion Polymerization: Fundamentals and Methods of Investigation
Journal of Applied Polymer Science, EarlyView.ABSTRACT The current understanding of fouling in emulsion polymerization is summarized from an engineering perspective and from a physical‐chemistry perspective. Emulsion polymerization in semibatch mode offers better control over the number of particles and side reactions than batch mode. Both reaction fouling and particulate fouling are observed, the
