Abstract

Procedure for obtaining a sizing agent, characterized in that polyisocyanates, or mixtures of polyisocyanates of the diphenylmethane series, are reacted with N-alkyl-dialkanolamines with 3-12 carbon atoms, and optionally, actuating compounds such as chain interrupters containing a group reactive with respect to isocyanate, and its aminonitrogen atoms are protonated or quaternized at least partially by reaction with an acid and/or a quaternizing agent and this oligourethane carrying protonized and/or quaternized ammonium groups and showing a molecular weight of 300-5000 dissolves in water or in mixtures of water and water-miscible solvents.
