Document Type and Number:
WIPO Patent Application WO/2020/045339
Kind Code:

Abstract:
The present invention provides a method for producing a polymer latex, which comprises a step wherein an organic solvent is removed by distillation from an emulsion that is obtained by mixing an aqueous solution of an emulsifying agent with a solution or dispersion liquid of a polymer, said solution or dispersion liquid being obtained by dissolving or dispersing the polymer in the organic solvent. With respect to this method for producing a polymer latex, the removal of the organic solvent from the emulsion by means of distillation is performed within a container in which the pressure is controlled to 0.02 MPa or more in terms of a gauge pressure.
