摘要:
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, b is 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.

摘要:
Short-chain perfluoroalkylethyl methacrylates copolymerized with vinyl chloride and/or vinylidene chloride, a C12-C22 alkyl(meth)acrylate and one or more thermally crosslinkable or isocyanate-reactive monomers are useful for oil-, water- and soil-repellent finishing of fibrous substrates under particularly mild conditions.
