ABSTRACT:
Amine-containing dispersants, such as succinimides, Mannich Bases and Viscosity-index improvers are reacted with fluorophosphoric acid. The reaction of the dispersant with the fluorophosphoric acid passivates the dispersant to fluorocarbon compositions used as seals, for example in automobile engines.
