ABSTRACT:
Polyoxylalkylene ether with an average molecular weight of 400 to 10,000 with at least one terminal hydroxyl group and at least one lateral --SO.sub.3 X group (X=hydrogen, alkali metal or ammonium ion) is disclosed. The polyoxyalkylene ether is obtainable by the statistical or blockwise addition reaction of (a) .alpha.-alkylene oxides with 2 to 14 carbon atoms or mixtures thereof and (b) allyl and/or methallyl glycidyl ethers to monohydric to quadrihydric aliphatic alcohols with up to 8 carbon atoms, the ratio of component (a) to component (b) being selected so that at least one allyl ether group is linked to the average molecule, reacting the polymer by a known reaction with, based on the allyl ether groups, at least equimolar amounts of a compound of the formula HSO.sub.3 Y (Y=alkali or ammonium ion) and if necessary, exchanging the cation Y against a hydrogen ion also by a known procedure.
The compounds are suitable as polyol components for the preparation of stable, ionic, aqueous polyurethane dispersions with a high solids content.
