ABSTRACT:
The invention relates to a process for the production of liquid, storage-stable isocyanate mixtures with a low color index having carbodiimide-(CD) and/or uretone imine (UI) groups, the isocyanate mixtures that can be obtained by this process and their use for the production of blends with other isocyanates or for the production of isocyanate group-containing pre-polymers and also of polyurethane plastics, preferably polyurethane foamed plastics.
