摘要
Fluorine-containing acrylic products obtained by telomerisation of: (a) 2 to 40 % of one or more thiols RF-B-SH where RF denotes a perfluoroalkyl radical and B an alkylene radical; (b) 20 to 70 % of one or more polyfluorinated monomers of general formula: IMAGE where Rf denotes a perfluoroalkyl radical, Q denotes an oxygen or sulphur atom, D is a divalent chain sequence linked to Q by a carbon, one of the symbols R denotes a hydrogen atom and the other a hydrogen atom or an alkyl radical; and (c) 0 to 65 % of one or more monomers of any kind, other than those defined under (b). These telomers, which are soluble in solvents which may be unhalogenated, are particularly well suited for making leathers water-repellent and oil-repellent. They can also be applied to other substrates.
