    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.

    摘要翻译： 阴离子低聚物，其通式为：其中T表示基团，任选地与OH基团的混合物中; u = 0或1; p = 1或2; M = H，Na，K，铵或单 - ，二 - 或三 - （烷基或羟烷基）铵基团，烷基部分含有1至4个碳原子; n = 5-30; z = 1-6; 并且R表示价数z的脂族，脂环族，芳基，烷基芳基或芳烷基，其可以含有1个或更多个氧原子，式（I）可能含有少量的分子间或分子内分子， 双环氧化物。 通过在路易斯酸存在下，将1摩尔的表卤代醇和任选的少量双环氧化物加入1摩尔的化合物R（OH）z（II）中，得到的多卤素化合物制备这些低聚物 然后通过与硫代酸，巯基乙酸或α-巯基丙酸或β-巯基丙酸的盐或酯反应转化成多硫代羧酸化合物，并且所得化合物在皂化后，如果合适，被酸化并用NaOH，KOH， NH 4 OH或胺，并且任选被氧化或亚砜化。 含有低聚物（I）的组合物适用于治疗角蛋白纤维，纺织品和水。
