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 compounds
