ABSTRACT:
Residual unreacted monomer, such as vinyl chloride monomer, is removed from an aqueous latex of polymer, such as polyvinyl chloride, by allowing the latex to flow as a thin liquid film down the inner surface of a substantially vertical column at subatmospheric pressure countercurrent to an ascending flow of steam. If desired, packing may be inserted in the column to enhance the removal of residual monomer.
