Title (EN) METHOD FOR PRODUCING A STORAGE-STABLE AND COLORLESS LIQUID POLYISOCYANATE COMPOSITION POSSESSING CARBODIIMIDE AND/OR URETONIMINE GROUPS
(FR) PROCEDE DE PRODUCTION D'UNE COMPOSITION DE POLYISOCYANATE LIQUIDE STABLE AU STOCKAGE ET INCOLORE POSSEDANT DES GROUPES CARBODIIMIDE ET/OU URETONIMINE
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.
(FR) L'invention concerne un procédé de production d'une composition de polyisocyanate liquide stable au stockage et incolore possédant des groupes carbodiimide et/ou urétonimine, qui consiste a) à condenser un polyisocyanate en présence d'un catalyseur choisi dans le groupe composé de phospholènes, phosopholidines et/ou de leurs oxydes, et b) à arrêter la condensation par addition du chlorure d'acide adipique comme poison de catalyseur.
