Fluoropolymer dispersion containing the pH dependent surfactants and methods for removing the fluorinated emulsifier from the fluoropolymer dispersion using a pH-dependent and surfactant anion exchange resin

摘要

A process of reducing the amount of fluorinated emulsifiers in fluoropolymer dispersions by contacting the fluoropolymer dispersion with an anion exchange resin in the presence of a pH-dependent surfactant, and fluoropolymer dispersions containing the pH-dependent surfactant and uses thereof.
