Patent number: 10246604Abstract: To provide a method for producing an aqueous liquid containing a vinyl polymer, of which the production efficiency is high, without lowering the yield of the vinyl polymer. When removing a hydrophilic organic solvent from a mixed liquid comprising a vinyl polymer, the hydrophilic organic solvent and water to produce an aqueous liquid containing the vinyl polymer, a liquid phase and a gas phase are formed in a closed container, a part of the liquid of the liquid phase is formed into small droplets and brought into contact with the gas phase to vaporize the hydrophilic organic solvent, and the vaporized hydrophilic organic solvent is removed from the closed container.Type: GrantFiled: July 31, 2017Date of Patent: April 2, 2019Assignee: AGC Inc.Inventors: Shintaro Fukunaga, Katsuya Ueno, Akio Ogawa, Yutaka Ohyama, Teruhiko Yasuda
