| titleOfInvention | Process for the production of isocyanurate polyisocyanates and products by the process |
| abstract | ABSTRACT OF THE INVENTION The instant invention is directed to a process for the production of isocyanate polyisocyanates containing at least 50%, by weight, of tris-isocyanatomonoisocyanurates and at most 3%, by weight, of isocyanurate-free diisocyanate. The process comprises catalytically trimerizing the organic diimocyanates free from isocyanurate groups and terminating the trimerization reaction by desactivation of the catalyst after 5 to 40% of the isocyanate groups of the isocyanurate-free diisocyanate have been trimerized. The unreacted isocyanurate-free diisocyanate is then distilled off in the presence of from 1 to 30%, by weight, based on the end product obtained as distillation residue, of an inert liquid distillation aid which boils at a temperature at least 50°C above the boiling point of the isocyanurate-free diisocyanate. The invention is also directed to the products produced by this process. |
