ABSTRACT:
Carboxylic amide dispersants are reacted with a fluorine-containing acid reagent selected from fluorophosphoric acid, boron trifluoride, fluoboric acid and the ammonium salts thereof. The reaction of the dispersant with the fluorine-containing acid passivates the dispersant to fluorocarbon compositions used as seals, for example in automobile engines.
