Abstract: Wäßrige, kolloidale Dispersionen von Fluorpolymeren können nach Zusatz eines Stabilisierungsemulgators durch Ultrafiltration (Teil A) über übliche semipermeable Membranen auf hohe Feststoffgehalte aufkonzentriert werden, wenn für die Förderung Pumpen verwendet werden, die die Dispersion berührungsfrei von Reibungskräfte hervorrufenden Teilen halten. Ein erheblicher Anteil des zugesetzten Stabilisierungsemulgators und hohe Anteile des ursprünglich von der Emulsionspolymerisation her in der Fluorpolymeren-Dispersion enthaltenen fluorhaltigen Emulgators können dabei über das wäßrige Permeat abgeführt werden. Durch einen nachgeschalteten basischen Anionenaustauscher (Teil B), kann der fluorhaltige Emulgator zurückgewonnen werden, in dem aus dem Anionenaustaucher abfließenden Filtrat kann der darin enthaltene Stabilisierungsemulgator durch Reversosmose (Teil C) aufkonzentriert und gegebenenfalls in den Ultrafiltrationsprozeß zurückgeführt werden. Es können Fluorpolymeren-Dispersionen gewonnen werden, die sich neben einem hohen Feststoffgehalt durch besonders niedrige Gehalte an fluorhaltigem Emulgator und an Stabilisierungsemulgator auszeichnen. Das Verfahren ist auf alle bekannten wäßrigen kolloidalen Dispersionen von fluorierten Homo- und Copolymeren anwendbar.
