Title
(EN) METHOD FOR PRODUCING A STORAGE-STABLE AND COLORLESS LIQUID POLYISOCYANATE COMPOSITION POSSESSING CARBODIIMIDE AND/OR URETONIMINE GROUPS
Abstract
(EN)
Method for producing a storage-stable and colorless liquid polyisocyanate composition possessing carbodiimide and/or uretonimine groups comprising the steps of a) condensing a polyisocyanate in the presence of a catalyst selected from the group consisting of phospholenes, phospholidines and/or their oxides, and b) stopping the condensation by adding adipoylchloride as catalyst killer. ┬ęKIPO&WIPO 2008
