| description | A process for the preparation of polyisocyanates containing iminooxadiazinedione groups, comprising reacting at least one (cyclo)aliphatic diisocyanate in the presence of at least one oligomerization catalyst, and when the reaction has reached a predeterminable degree of con-version, based on the (cyclo)aliphatic diisocyanates, stopping the reaction by addition of at least one catalyst poison for the oligomerization catalyst, wherein the oligomerization catalyst is a salt containing a fluoride or poly(hydrogen)fluoride [F- x (HF)m] as anion and the catalyst poison is a solution containing at least one alcohol comprising at least 6 carbon atoms as solventand wherein m is a number between 0.01 and 20.
L'invention concerne un procédé pour la préparation de polyisocyanates contenant des groupes iminooxadiazinedione, comprenant la réaction d'au moins un diisocyanate (cyclo)aliphatique en présence d'au moins un catalyseur d'oligomérisation et, lorsque la réaction a atteint un degré prédéterminable de conversion, sur la base des diisocyanates (cyclo)aliphatiques, l'arrêt de la réaction par l'addition d'au moins un poison de catalyseur pour le catalyseur d'oligomérisation, le catalyseur d'oligomérisation étant un sel contenant un fluorure ou poly(fluorure d'hydrogène) [F- x (HF)m] en tant qu'anion et le poison de catalyseur étant une solution contenant au moins un alcool comprenant au moins 6 atomes de carbone en tant que solvant et m étant un nombre compris entre 0,01 et 20. |
