A terpolymer having units of Formula IwhereinX is a C2-10 alkyl, C6-12 aryl, or C4-12 alkoxy radical,d is from about 3 to about 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, andf 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. |
