| abstract |
The present invention provides a method for producing a purified fluoropolymer aqueous dispersion, comprising: (A) bringing a fluoropolymer aqueous dispersion obtained using a hydrocarbon surfactant into contact with an anion exchange resin A or a synthetic adsorbent,wherein the anion exchange resin A has:an ion-exchange group represented by the following general formula (A1): -N<sup>+</sup>R<sup>1</sup>R<sup>2</sup>R<sup>3</sup>X<sup>-</sup>wherein R<sup>1</sup>, R<sup>2</sup>, and R<sup>3</sup> are the same as or different from each other, and are each a hydrogen atom or an organic group, and at least one of R<sup>1</sup>, R<sup>2</sup>, and R<sup>3</sup> is an organic group having 3 or more carbon atoms; and X is a counter ion; oran ion-exchange group represented by the following general formula (A2): -NR<sup>4</sup>R<sup>5</sup>wherein R<sup>4</sup> and R<sup>5</sup> are the same as or different from each other, and are each a hydrogen atom or an organic group, and at least one of R<sup>4</sup> and R<sup>5</sup> is an organic group having 2 or more carbon atoms. |
