A surfactant of formula (1) A surfactant of formula 1 (Rf-A)a-Q-([B]k-R)b Formula 1 wherein a and b are each independently 1 or 2; Ris a linear or branched perfluoroalkyl radical having from 2 to about 20 carbon atoms, optionally interrupted with at least one oxygen; R is a Cto Clinear, branched or cyclic alkyl, or a Cto Caryl; B is-(CHCHRO)k is 0 or 1, x is 1 to about 20, A is-(CH)[(CHRCHO)]-[(CH)(CH)CHOH(CH)m]-, wherein each m is independently 0 to 3, s is 0 to about 30, t is 0 or 1, and e is 0 or 1, Ris H or CHQ is:-OP(O)(O-M)(O)-,-O-,-S-(CH)-C(O)-O-,-SO-O--CHCHO-C(O)CHC(OH)(V)CHC (O)O-;-(CHCHO)CHCH(OH)-(CHCHO)-(CH)-Si[OSi(R)]-,-SONR--(CHCHO)C(O)CH(SO-M)CHC(O)(OCHCH)-wherein z is 1 to about 15, or a bond when s is a positive integer, V is-C(O)ORand Ris H, CHor R; Ris Cto Calkyl, and Mis a Group 1 metal or an ammonium (NHRy)cation wherein x + y = 4, and Ris Cto Calkyl, provided that when Q is-OP(O)(OM)(O)-or when Q is-(CHCHO)-C(O)CH(SO-M+)CHC(O)(OCHCH)-then at least one of s or e is a positive integer.
