The present invention comprises fluorinated ethoxylated polyurethanes of formula [Rf-(X)n-(CH2CHR1-O)m-CH2CH2-O-C(O)-NH]p-A, wherein Rf is a C1 to C6 perfluoroalkyl; X is a divalent radical; n is 0 or 1; R1 is H or C1 to C4 alkyl; m is 1 to 20; p is a positive integer of at least 2; and A is the residue of a polyisocyanate, and methods for altering surface behavior of liquids using such compounds. La présente invention porte sur des polyuréthanes éthoxylés fluorés de formule [Rf-(X)n-(CH2CHR1-O)m-CH2CH2-O-C(O)-NH]p-A, dans laquelle Rf représente un perfluoroalkyle en C1 à C6 ; X représente un radical divalent ; n vaut 0 ou 1 ; R1 représente H ou alkyle en C1 à C4 ; m est 1 à 20 ; p est un entier positif d'au moins 2 ; et A est le reste d'un polyisocyanate. L'invention porte également sur des procédés pour modifier le comportement de surface de liquides à l'aide de tels composés.
