Abstract

Perfluoropolyoxyalkylenes containing acid and/or ketonic groups are neutralized by reacting same in the liquid phase with elemental fluorine at temperatures of from -20° to +150°C in the presence of a supported catalyst consisting of fluorides of Ag, Pb, Co, Ni, Cu, Mn, V, Cr,or Fe.

In a preferred embodiment, a mixture of fluorides of the above mentioned metals and of fluorides, or fluoride precursors, of an alkali and/or alkaline-earth metal is used as catalyst, optionally supported on a suitable carrier.
