Abstract: The present invention relates to a process for producing polyisocyanates comprising reacting an isocyanate component in the presence of a mono- or multinuclear complex of titanium, zirconium and/or hafnium as catalyst to give polyisocyanates having a content of iminooxadiazinedione groups of ≥20 mol % based on the total amount of isocyanurate and iminooxadiazinedione groups. The present invention also provides polyisocyanates obtainable by the process according to the invention and both polyurethanes and polyureas obtainable by reacting the polyisocyanates with at least one hydroxy-functional or amino-functional component respectively.
