| 摘要 |
The present invention relates to reactive polyurethanes having a low monomer ic diisocyanate content and also to their preparation and their use in reactive one- and two-component adhesives/sealants, assembly foams, casting compounds, and als o 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.
