发明名称 POLYISOCYANATES WHICH CONTAIN CARBODIIMIDE AND/OR URETONE IMINE GROUPS AND ARE STABLE IN STORAGE
摘要 The instant invention relates to a process for producing stable equilibrium mixtures of carbodiimides, uretone imines and organic isocyanates and storage-stable solutions of carbodiimides and uretone imines in polyisocyanates which are free from carbodiimide groups. Either the carbodiimide, or the uretone imine, or both, may contain isocyanate groups. The invention relates to the process for the preparation of these products by so-called heterogeneous catalysis and the use of these products for the production of polyurethane resins.
