| description | The application relates to a catalyst kit comprising a trimerisation catalyst for the asymmetric trimerisation of polyisocyanates and a catalyst poison for the trimerisation catalyst, which is characterised in that the trimerisation catalyst and the catalyst poison each have a water content of at most 0.5 wt %. The application furthermore relates to the use of the catalyst kit for the preparation of polyisocyanates containing iminooxadiazinedione groups by oligomerisation of monomeric di- and/or triisocyanates and a process for the preparation of polyisocyanates containing iminooxadiazinedione groups. |
