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