A process for reducing fluorosurfactant content of a stabilized
fluorosurfactant-containing aqueous fluoropolymer dispersion comprising
contacting the stabilized fluorosurfactant-containing aqueous
fluoropolymer dispersion with an anion exchange resin comprising a
polymer and quaternary ammonium functional groups to reduce
fluorosurfactant content, the functional groups being resistant to
degradation which releases trialkylamines. The anion exchange resin is
separated from the dispersion after the fluorosurfactant content has been
reduced.
