ABSTRACT:
Fluorochemical surfactant compositions are provided. The compositions comprise a fluorochemical amine salt which can be represented by the formula: ##STR1## wherein R.sub.f is a perfluoroaliphatic radical containing 3 to 20 carbon atoms, R is H or CH.sub.3, and R.sup.1 is an alkyl radical containing 1 to 4 carbon atoms. The fluorochemical surfactant compositions are prepared by reacting at least one perfluoroalkyl sulfonyl fluoride having 3 to 20 alkyl carbon atoms, ethylene or propylene oxide, and at least one tertiary amine, (R.sup.1).sub.3 N wherein R.sup.1 is an alkyl radical having 1 to 4 carbon atoms and which may contain a hydroxyl group.
