Beschreibung
Zusammenfassung:	Claimed are fluorous telomeric compounds of the formula: RF-A-[CH2]cCR2R3-Z where RF is a perfluoroalkyl radical of 1 to 20 carbon atoms, A is a group of the formulae, R1 is CF3 OR4, Cl, Br or I, R2 and R3 are H, alkyl or aryl R4 is perfluoromethyl, perfluoropropyl or perfluoropropyloxypropyl X and Y are H, Cl or F Z is -OH, -OCOCH=CH2 or -OCOCCH3=CH2 a is from 0 to 10, bis from 1 to 30 and c 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.
