| abstract | A PROCESS FOR THE PRODUCTION OF POLYISOCYANATES WHICH HAVE A BIURET STRUCTURE ABSTRACT OF THE DISCLOSURE The present invention is directed to a process for the production of polyisocyanates which have a biuret structure by reacting aliphatic diisocyanates with water at elevated temperature, characterized in that the reaction is carried out in the presence of: a) .alpha.,.alpha.,.alpha.-tri-substituted acetic acids, which do not have any further isocyanate-reactive group other than the carboxyl group, and/or b) anhydrides of acids of the type mentioned in a) wherein up to 0.39 mols of component (a) are used per mol of water, up to about 2 mols of component (b) are used per mol of water, and the total quantity of components (a) and (b) is at least 0.02 to about 2 mols per mol of water. |
