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.
