摘要：
A compound comprising Formula I, or a mixture thereof, wherein Y is a bond or CmH2m−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 (CH2CH2)2NCH2CH2OA or (CH2CH2)2O, provided that when X and X′ combine to form (CH2CH2)2O then Y is CH2CH(OA)CH2, A is CF2CFHO—Rf or H, Rf is CnF2n+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—Rf, and its use in lowering surface tension and imparting improved surface effects.
