A terpolymer having units of Formula (I), wherein X is a C2-10 alkyl, C6-12 aryl, or C4-12 alkoxy radical; d is from about 3 to 50; R is a fluoroalkyl radical Rf-(A)v-(B)w-; Rf is a fully fluorinated straight or branched aliphatic radical optionally interrupted by at least one oxygen atom; A is a divalent radical selected from -SO2N(R'')-, -CON(R'')-, -S-, or -SO2-, where R'' is H, or a C1-6 alkyl radical; B is a divalent linear hydrocarbon radical - CtH2t-, where t is 1 to 12; Y is a divalent radical -CH2-O-; u, v, and w are each independently zero or 1; R' is hydrogen or methyl; e is from about 0.05 to about 10; M is hydrogen, alkali metal, or ammonium; and f is from about 5 to about 40; and its use to provide soil resistance and resistance to staining by acid dyes for fiber substrates is disclosed.
L'invention concerne un terpolymère renfermant des unités de formule (I), dans laquelle X est un radical alkyle C¿2?-C¿10?, aryle C¿6?-C¿12? ou alcoxy C¿4?-C¿12?; d est compris entre 3 et 50 environ; R est un radical fluoroalkyle R¿f?-(A)¿v?-(B)¿w?; R¿f? est un radical aliphatique fluoré droit ou ramifié, éventuellement interrompu par au moins un atome d'oxygène; A est un radical bivalent choisi entre SO¿2?N(R''), CON(R''), S ou SO¿2?, où R'' est H ou un radical alkyle C¿1?-C¿6?; B est un radical hydrocarboné linéaire bivalent C¿t?H¿2t?, où t est compris entre 1 et 12; Y est un radical bivalent CH¿2?-O; u, v et w sont indépendamment 0 ou 1; R' est hydrogène ou méthyle; e est compris entre 0,05 et 10 environ; M est l'hydrogène, un métal alcalin ou l'ammonium; et f est compris entre 5 et 40 environ. L'invention concerne également l'utilisation dudit terpolymère pour conférer à des substrats fibreux la résistance aux salissures et la résistance aux taches dues à des pigments acides.
