METHOD OF IMPROVING FLUORINATED SURFACTANTS Abstract of the Disclosure Surface properties of solutions of fluorinated surfactants are improved by employing a fluorinated synergist (Rf)nTmZ wherein Rf is a perfluorinated aliphatic group, T is alkylene, arylene, alkylenethio alkylene, alkyleneoxyalkylene or alkyleneiminoalkylene, Z is a neutral or a polar group, n is 1 or 2 and m is 0 to 2, and/or a magnesium salt. The resulting synergistic surfactant compositions are useful for all appli-cations where surfactants are employed. |
