Abstract
The present invention relates to a single-stage process for preparing polyurethanes which comprise at least three hydrophilic sections, at least four hydrophobic sections, optionally allophanate segments and optionally isocyanurate segments, in the presence of alkali(ne earth) metal carboxylates or zinc carboxylates. Furthermore, the present invention relates to the polyurethanes themselves obtainable in this way, to the use thereof as thickeners for aqueous preparations, and to aqueous preparations comprising polyurethanes of this type.
