Abstract

Fluorozott emulgeálószerek kis mennyiségű fluorpolimer részecskéttartalmazó vizes fázisból úgy nyerhetők ki, hogy a vizes fázist kismennyiségű, nemionos felületaktív szerrel kezelik, az ily módon kezeltvizes fázist anionos ioncserélő gyantával hozzák érintkezésbe, és azadszorbeált emulgeálószert az ioncserélő gyantáról felszabadítják. Afinomeloszlású fluorpolimer flokkulálószer alkalmazásávalkvantitatívan ki csapható a kezeletlen vizes fázisból vagy azeluátumból. Ó
