Abstract

Procedure for obtaining liquid aromatic polyisocyanates, which carry sulfonic acid groups and/or sulfonate groups, characterized in that liquid mixtures of various components of aromatic polyisocyanates, which have an NCO content of 10 to 42% by weight and a viscosity of 50 to 10,000 cP at 25ºC, mix with 0.1-10% by weight of sulfur trioxide, or an equivalent amount of oleum, sulfuric acid or chloro sulfonic acid, at -20 to 200ºC, and allow to finish react, and the sulfonation products obtained in this way, if necessary, are totally or partially neutralized with a basic compound.
