Fluorochemical compound useful for textile treatment

Claim 1

A fluorochemical compound having the formula (R f Q) e (XCO) m A(COOM) p where R f is fluorinated aliphatic radical having from three to twenty carbon atoms and containing about 40-78 weight percent carbon-bonded fluorine, "Q" is a divalent linking radical selected from the group consisting of --(CH 2 ) n --, --SO 2 NR 1 (CH 2 ) n --, --(CH 2 ) n COOCH 2 CH 2 --, --SO 2 NR 1 (CH 2 CH 2 O) n CH 2 CH 2 , --SO 2 (C 2 H 5 )C 2 H 4 NHC 2 H 4 -- and --SO 2 ##STR22## wherein "R 1 " is hydrogen or a lower alkyl group having from about 1 to 14 carbon atoms and "n" is an integer from about 1 to 15, "M" is a cation selected from NH 4 + , Na + , K + , Li + , H + or is a protonated alkyl amine having from 1-6 carbon atoms in the alkyl group, "A" is a polyvalent organic radical having a valency of m+p and is the residue obtained by eliminating the carboxyl groups of a polybasic organic acid or an organic anhydride and is selected from the group consisting of maleic, succinic, phthalic, tetrachlorophthalic, chlorendic, tetrabromophthalic, 3-nitrophthalic, 4-nitrophthalic, cis 1,2-cyclohexane dicarboxylic, 5-norborene-2,3-dicarboxylic, 1,8-naphthalene dicarboxylic and benezophenone tetracarboxylic and pyromellitic, "X" is NR (wherein R is hydrogen or an alkyl group of from 1 to 14 carbon atoms), or N and "e", "p" and "m" are integers of 1 or 2.
