Manner in order to remove the fluorine conversion emulsifier from fluoro polymer distributed ones making use of anion exchange resin and the pH dependant surface active agent and fluoro polymer distributed ones which contain the pH dependant surface active agent

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.
