Zusammenfassung:	Claimed are fluorous telomeric co mpounds of the formula: RF - A - [CH2]cCR2R3 - Z where RF is a perfluoroalkyl radical o f 1 to 20 carbon atoms, A is a group of the formulae (I) or (II). 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 fro m 0 to 10, b is fro m 1 to 30 and c is fro m 1 to 30. These co mpounds are copolymerized wit h further mo no mers. The copolymers thus obtained are useful for water-, oil- and soil-repellent finishing of fibrous substrates. L'invention concerne des composés télomères fluorés de formule : RF - A - [CH2]cCR2R3 - Z où RF est un radical perfluoroalkyle de 1 à 20 atomes de carbone, A est un groupe de formule [formule]:; R1 est CF3, OR4, Cl, Br ou I; R2 et R3 sont chacun H, un alkyle ou un aryle; R4 est un groupe perfluorométhyle, perfluoropropyle ou perfluoropropyloxypropyle; X et Y sont chacun H, Cl ou F; Z est -OH, -OCOCH=CH2 ou -OCOCCH3=CH2; a vaut de 0 à 10, b vaut de 1 à 30 et c vaut de 1 à 30. Ces composés sont copolymérisés avec d'autres monomères. Les copolymères ainsi obtenus sont utiles pour la finition hydrofuge, oléofuge et anti-salissures de substrats fibreux.
