<p>Claimed are fluorous telomeric compounds of the formula R<SUB>F</SUB> - A -SO<SUB>2</SUB> - Z, where R<SUB>F</SUB> is a perfluoroalkyl radical of 1 to 20 carbon atoms; A is a group of the formulae (I) or (II); R<SUP>1</SUP> is CF<SUB>3</SUB>, OR<SUP>4</SUP>, Cl, Br or I; R<SUP>2</SUP> is H or alkyl of 1 to 6 carbon atoms; R<SUP>3</SUP> is alkylene of 1 to 13 carbon atoms; R<SUP>4</SUP> is perfluoromethyl, perfluoropropyl or perfluoropropyloxypropyl; X and Y are H, Cl or F; Z is -OH, -Cl, -OM, -N(R<SUP>2</SUP>)R<SUP>3</SUP>OH, -N(R<SUP>2</SUP>)R<SUP>3</SUP>OCOCH = CH<SUB>2</SUB> or - Z N(R<SUP>2</SUP>)R<SUP>3</SUP>OCOCCH<SUB>3</SUB> = CH<SUB>2</SUB>; M is an alkali metal, ammonium or a mono-, di-, tri- or tetra-C<SUB>1</SUB>-C<SUB>4</SUB>- alkylammonium cation; a is from 0 to 10 and b is from 1 to 30. These compounds are copolymerized with further monomers. The copolymers thus obtained are useful for water-, oil- and soil-repellent finishing of fibrous substrates.</p> |
