Abstract:
The invention relates to a process for the preparation of liquid, storage-stable isocyanate mixtures of low color number containing carbodiimide (CD) and/or uretonimine (UI) groups, the isocyanate mixtures obtainable by this process and the use thereof for the preparation of blends with further isocyanates and for the preparation of prepolymers containing isocyanate groups and of polyurethane plastics, preferably polyurethane foams.
