PROCESS FOR THE PREPARATION OF NEW, WATERSOLUBLE, REACTIVE FLUORINATED COMPOUNDS

摘要

New water-soluble or water-dispersible reactive perfluoroalkylated compounds, characterized in that they correspond to the general formula (I) wherein the reactive group is away from the perfluoroalkyl radical. They may react easily with amines, alcohols, thiols and carboxilic acids; they are thus used as fluoroalkylent agents in oleophoby and/or hydrophoby techniques, particularly in the fluoroalkylation of derivatives of proteins, polyols or polysaccharides. RF is a linear or branched perfluoro or polyfluoroalkyl containing from 4 to 20 carbon atoms, p is an integer from 0 to 1, n is an integer from 0 to 3, m is an integer from 3 to 6, A is a -SO2- radical, or a simple bond, (a) is imino or imino substituted by alkyl, oxygen or sulphur, (b) is imino, alkylimino or dialkylammonium, oxygen or sulphur, B is -CO- radical, or a simple bond, Y is a radical (c), or (d) wherein R is a hydrogen atom or an alkyl radical.
