Function analysis for continuous emulsion polymerization of vinyl acetate was conducted by functional module representation method based on the idea of Freund and Sundmacher (2008). The information derived from the function analysis was utilized in process intensification in continuous emulsion polymerization using a compartment reactor consisting of three mixing compartments. A reactor for continuous emulsion polymerization was decomposed into four functional modules; contacting, activating, chemical reaction and polymer growth. The first, second and third compartments were assigned to contacting-activating, chemical reaction and polymer growth zones, respectively. A two-bladed paddle impeller was used in the first compartment, while rotating disks were used in the second and third compartments. The feasibility of continuous emulsion polymerization using this compartment reactor was investigated. This compartment reactor successfully produced not only a high monomer conversion but also a stable and mono-dispersed particle size distribution. Based on this feasibility study, a new representation of functional modules with a multi-layer structure was proposed.
