ABSTRACT:
A process for continuously stripping a polymer dispersion comprising a heat exchanger with minimal internal obstructions for the stripper. The process is particularly adapted to dispersions that are heat and shear sensitive. The process is able to extract hydrophobic VOC's more efficiently than a single, jacketed tube design.
