Abstract

Gegenstand der Erfindung ist ein Verfahren zur Hydrolyse von mindestens einem Isocyanataddukt, mit einem Hydrolysemittel, dadurch gekennzeichnet, dass das Hydrolysemittel Wasser und zumindest ein Imidazol der folgenden Strukturformel enthält wobei der Rest R1 ein Alkylrest mit 1 bis 5 Kohlenstoffatomen, bevorzugt 1 bis 3 Kohlenstoffatomen, weiter bevorzugt 1 bis 2 Kohlenstoffatomen und besonders bevorzugt mit einem Kohlenstoffatom ist und die Reste R2, R3 und R4 unabhängig voneinander Wasserstoff (H) sind oder Alkyreste sind mit 1 bis 5 Kohlenstoffatomen, bevorzugt 1 bis 3 Kohlenstoffatomen, weiter bevorzugt 1 bis 2 Kohlenstoffatomen und besonders bevorzugt mit einem Kohlenstoffatom. Ferner umfasst die Erfindung auch die Verwendung von Ausgangsstoffen für das genannte Verfahren.
