CA 2149957

A resin which contains perfluoroalkyl groups and which is soluble, emulsifiable or dispersible in water, identical with that prepared by reacting a) at least one sulphonamide containing a perfluoroalkyl group of the formula Image wherein Rf is a monovalent perfluoroalkyl group with 4 to 20 carbon atoms, and R1 represents hydrogen or a monovalent hydrocarbon chain with 1 to 20 carbon atoms, optionally interrupted by 1 to 4 oxygen atoms, b) a component which contains oxyethylene units and which contains groups which react with 1,2-epoxide groups, c) a component which contains 1,2-epoxide groups, and d) optionally at least one additional component which contains a group which reacts with 1,2-epoxides, oxyethylene units present in the resin constituting about 5 to 95% by weight of the total resin. The product is suitable for making aqueous solutions, emulsions and dispersions useful for the protective treatment of minerals, textiles, leather and paper.
