A compound comprising Formula I, or a mixture thereof, wherein Y is a bond or C m H2m-p(OA)p wherein m is 0 to 4, and p is 0 or 1, X' is X or H, X is CH2CH2OA, CH(CH2OA)2, C(CH2OA)3, or X and X' combine to form (CH2H2)2NCH2CH2OA or (CH2CH2)2O, provided that when X and X' combine to form (CH2CH2)2O then Y is CH2CH(OA)CH2, A is CF2CFHOR f or H, R f is C n F2n+1 wherein n is an integer of 1 to about 6, M is a cation having a charge equal to a, and a is a positive integer equal to 1 or 2, provided that at least one of X, X', or Y contains A equal to CF2CFHO-R f, and its use in lowering surface tension and imparting improved surface effects.

La présente invention concerne un composé de formule (I), ou un mélange de celui-ci, dans laquelle: Y est une liaison ou CmH2m-p(OA)p où m est 0 à 4, et p est 0 ou 1, X' est X ou H, X est CH2CH2OA, CH(CH2OA)2, C(CH2OA)3, ou X et X' forment ensemble (CH2H2)2NCH2CH2OA or (CH2CH2)2O, à condition que lorsque X et X' forment ensemble (CH2H2)2NCH2CH2OA or (CH2CH2)2O, alors Y est CH2CH(OA)CH2, A est CF2CFHORf ou H, Rf est CnF2n+1 où n est un nombre entier de 1 à environ 6, M est un cation ayant une charge égale à a, et a est un nombre entier positif égal à 1 ou 2, à condition qu'au moins un parmi X, X', ou Y contienne A égal à CF2CFHO-Rf. L'invention concerne également l'utilisation dudit composé pour réduire la tension superficielle et procurer des effets de surface améliorés.
