A process for reducing fluorosurfactant content of a stabilized
fluorosurfactant-containing aqueous fluoropolymer dispersion. The process
includes providing a fixed bed of anion exchange resin having anion
exchange groups with counter ions. The anion exchange resin is treated to
replace at least some the counter ions with counter ions of
non-fluorinated anionic surfactant. The stabilized
fluorosurfactant-containing aqueous fluoropolymer dispersion is passed
through the treated fixed bed of anion exchange resin.
