PROCESS FOR REMOVING FLUORINATED EMULSIFIER FROM FLUOROPOLYMER DISPERSIONS USING AN ANION-EXCHANGE RESIN AND A PH-DEPENDENT SURFACTANT AND FLUOROPOLYMER DISPERSIONS CONTAINING A PH-DEPENDENT SURFACTANT

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.
