  • Method and apparatus for removal of unreacted monomer from synthesized high polymer latex
    Patent number: 4032497
    Abstract: From a synthesized high polymer latex, the unreacted monomer remaining therein can be removed efficiently by causing a hollow cylinder inclined by a gradient of 1/100 to 1/10 with reference to the horizontal plane to be rotated around its axis, then introducing the synthesized high polymer latex and a gas containing moisture into the interior of the hollow cylinder which is maintained in continuous rotation and allowing the latex and the gas to come into mutual contact within the hollow cylinder.
