    Abstract: The present invention relates to a one-stage method for producing polyurethanes which contain at least three hydrophilic segments, at least four hydrophobic segments, optionally allophanate segments and/or isocyanurate segments and which are produced in the presence of alkaline earth metal carboxylates or zinc carboxylates. The present invention further relates to the thus obtained polyurethanes, to their use as thickener for aqueous preparations and to aqueous preparations containing such polyurethanes.
