Abstract

The efficiency of post-polymerization and devolatilization for residual monomer and VOC removal was investigated. It was found that mass transfer from aqueous phase to gas phase was the rate-determining step for devolatilization. The effect of the thermodynamic equilibrium coefficients on the latex devolatilization efficiency was studied. A strategy in which post-polymerization and devolatilization was applied simultaneously was found to be the most efficient one in both the removal of the residual monomer and VOC present in the latex, since it took advantage of both processes.
