    摘要： A process to substantially remove the fluorinated anionic surfactants from fluoropolymer dispersions comprising the following steps:

    a) addition to the fluoropolymer dispersion of an anionic polyelectrolyte;
    b) contact of the dispersion with an anionic exchanger;
    c) separation of the dispersion from the anionic exchanger and recovery of the dispersion substantially fluorinated anionic surfactant free.
