Kind Code:
A1
Abstract:
Provided is a fluoropolymer aqueous dispersion liquid production method for producing a fluoropolymer aqueous dispersion liquid containing a fluoropolymer, the method comprising: preparing an aqueous dispersion liquid containing a fluoropolymer by polymerizing a fluoromonomer in the presence of a fluorine-containing surfactant and an aqueous medium; adding a nonionic surfactant to the obtained aqueous dispersion liquid and adjusting the pH of the aqueous dispersion liquid to 7 or higher; adjusting the temperature of the aqueous dispersion liquid to 35°C or higher; and bringing the aqueous dispersion liquid containing the nonionic surfactant into contact with a treating agent.
