The present invention relates to reactive polyurethanes having a low monomeric diisocyanate content and also to their preparation and their use in reactive one- and two-component adhesives/sealants, assembly foams, casting compounds, and also flexible, rigid and integral foams. The polyurethanes are prepared in the presence of zirconium(IV) acetylacetonate complexes as catalyst, where at least one acetylacetonate ligand present in the catalyst bears a fluorine substituent.
