Ammonium und amine salts of acids having the formula
wherein Rf is a perfluoroalkyl group; R, is alkylene or substituted alkylene; X is -S-, -SO-, or -SO2-; R2 is hydrogen, alkyl, aryl, substituted aryl, -B-COOH or a -B-COOe anion; B is a covalent bond, arylene or alkylene; Z is the ammonium or amine cation; ⊖p is the anionic charge, ⊕q is the cationic charge; and p, and q, are the balanced mole equivalents respectively, are provided. These salts applied in the form of aqueous dispersions or emulsions, are useful in rendering cellulosic and natural and synthetic polyamide materials oil and water repellent.
