The invention relates to a method for the hydrolysis of at least one isocyanate adduct, with a hydrolyzing agent, characterized in that the hydrolyzing agent contains water and at least one imidazole of the following structural formula, where R1 is a alkyl group having 1 to 5 carbon atoms, preferably 1 to 3 carbon atoms, more preferably 1 to 2 carbon atoms, and most preferably having one carbon atom, and R2, R3 and R4 independently of each other are hydrogen (H) or are alkyl groups having 1 to 5 carbon atoms, preferably 1 to 3 carbon atoms, more preferably 1 to 2 carbon atoms, and most preferably having one carbon atom. The invention further relates to the use of starting substances for the described method. |
