PROCESS FOR PRODUCING AQUEOUS FLUOROPOLYMER DISPERSION |
摘要 |
<p>The invention provides a method of producing an aqueous fluoropolymer dispersion by which aqueous fluoropolymer dispersions high in fluoropolymer concentration can be prepared in a short period of time. The present invention provides a method of producing an aqueous fluoropolymer dispersion comprising a step (1) of adding a nonionic surfactant to an aqueous fluoropolymer dispersion to be treated, a step (2) of phase-separating into a supernatant phase and an aqueous fluoropolymer dispersion phase following the step (1), and a step (3) of recovering the aqueous fluoropolymer dispersion phase by removing the supernatant phase, stirring being provided in the step (2).</p> |
