    摘要: Anionic oligomers of the general formula: ##STR1## in which T denotes the radical ##STR2## optionally in a mixture with the OH radical; u=0 or 1; p=1 or 2; M=H, Na, K, ammonium or a mono-, di- or tri-(alkyl or hydroxyalkyl)ammonium group, the alkyl part containing 1 to 4 carbon atoms; n=5-30; z=1-6; and R denotes an aliphatic, alicyclic, aryl, alkylaryl or aralkyl radical of valency z, which can contain 1 or more oxygen atoms, it being possible for the formula (I) to contain minor proportions of intermolecular or intra-molecular branches originating from a bis-epoxide.These oligomers are prepared by the addition of n mols of epihalogenohydrin, and optionally of a minor proportions of bis-epoxide, to 1 mol of compoundsR(OH).sub.z (II),in the presence of a Lewis acid, the polyhalogen compounds obtained then being converted into polythiocarboxylic compounds by reaction with a salt or an ester of thiloactic acid, thioglycolic acid or .alpha.-mercaptopropionic or .beta.-mercaptopropionic acid, and the resulting compounds, after saponification, if appropriate, being acidified and neutralized with NaOH, KOH, NH.sub.4 OH or an amine, and optionally oxidized or sulphoxidized.The compositions containing oligomers (I) are suitable for the treatment of keratin fibres, textiles and water.
