Fluorine-containing urethanes represented by the general formula: [Rf-A1-Z-X1- OC(=O)NH-]mI[-NHC(=O)O-Y1]n[-NHC(=O)O-((ClCH2-)X2O)a-R1]k (1) wherein I is a group derived from a polyisocyanate by removal of the isocyanato groups; Rf is perfluoroalkyl of 1 to 21 carbon atoms; A1 is a direct bond or an organic group of 1 to 21 carbon atoms; Z is -S- or -SO2-; X1 is a divalent, straight- chain or branched, C1-5 aliphatic group which may have at least one hydroxyl group; X2 is a trivalent, straight-chain or branched, C2-5 aliphatic group; Y1 is a monovalent organic group which is optionally hydroxylated; and R1 is hydrogen or alkyl of 1 to 10 carbon atoms.

Uréthanes fluorés représentés par la formule générale : [Rf-A1-Z-X1-OC(=O)NH-]mI[-NHC(=O)O-Y1]n[-NHC(=O)O-((ClCH2-)X2O)a-R1]k (1) où I est un groupement dérivé d~un polyisocyanate par l~élimination des groupements isocyanato ; Rf est un perfluoroalkyle ayant de 1 à 21 atomes de carbone ; A1 est une liaison directe ou un groupement organique ayant de 1 à 21 atomes de carbone ; Z est -S- ou -SO2- ; X1 est un groupement aliphatique en C1-5 divalent, à chaîne linéaire ou ramifiée, pouvant contenir au moins un groupement hydroxyle ; X2 est un groupement aliphatique en C2-5 trivalent, à chaîne linéaire ou ramifiée ; Y1 est un groupement organique monovalent qui est éventuellement hydroxylé ; et R1 est un hydrogène ou alkyle ayant de 1 à 10 atomes de carbone.
