ABSTRACT:
The present invention provides a method of producing a fluororesin aqueous dispersion which can produce a fluororesin aqueous dispersion low in fluorine-containing surfactant concentration and high in polytetrafluoroethylene concentration with high efficiency. The invention provides a method of producing a fluororesin aqueous dispersion which comprises subjecting a crude fluororesin aqueous dispersion comprising a polytetrafluoroethylene particle dispersed in an aqueous medium to treatment with an ion-exchange resin and to treatment for concentration by phase separation in the presence of an electrolyte and/or a fluorine-free anionic surfactant.
