<p>Perfluoroalkylthio-substituted half esters and amides of succinic acid having the formula or its isomer, wherein Rf is perfluoroalkyl, R1 alkylene, optionally interrupted with oxygen, sulfur or nitrogen atoms, X is oxygen or NH, y is zero or 1, Q is a polyether or polyester diradical moiety having a molecular weight of 300 to 5000 or a polysiloxane having 5 to 90 repeating units and A is hydrogen, hydroxyl, amino, alkoxy, phenoxy, alkylphenoxy, dialkylamino, the group or its isomer. Said compounds being prepared by reacting e.g. maleic anhydride with a polyether, polyester, diamine or a polysiloxane derivative of an alcohol or a primary amine and then reacting the product with a perfluoroalkyl alkylene thiol. The novel compounds are useful as surfactants with specific applications as wetting agents in coatings waxes, emulsions, paints and resins.</p> |
