(EN) METHOD FOR PRODUCING LIQUID, STORAGE-STABLE ORGANIC ISOCYANATES COMPRISING CARBODIIMIDE AND/OR URETONIMINE GROUPS
(FR) PROCEDE DE PRODUCTION D'ISOCYANATES ORGANIQUES PRESENTANT DES GROUPES DE CARBODIIMIDES ET/OU D'URETONIMINES, LIQUIDES ET STABLES AU STOCKAGE
Abstract: front page image
(DE)Die Erfindung betrifft ein Verfahren zur Herstellung flüssiger, lagerstabiler Carbodiimid- (CD) und/oder Uretonimin- (UI) Gruppen aufweisender Isocyanatmischungen mit niedriger Farbzahl, die nach diesem Verfahren erhältlichen Isocyanatmischungen und deren Verwendung zur Herstellung von Abmischungen mit weiteren Isocyanaten bzw. zur Herstellung von Isocyanat- gruppen enthaltenden Prepolymeren sowie von Polyurethankunststoffen, vorzugsweise Polyurethanschaumstoffen.
(EN)The invention relates to a method for producing liquid, storage-stable isocyanate mixtures comprising carbodiimide (CD) and/or uretonimine (UI) groups, with low colour index. The invention also relates to the isocyanate mixtures obtained according to said method and to the use thereof for producing mixtures with additional isocyanates and/or for producing prepolymers containing isocyanate groups and polyurethane plastics, preferably, polyurethane foams.
(FR)L'invention concerne un procédé de production de mélanges d'isocyanates présentant des groupes de carbodiimides (CD) et/ou d'urétonimines (UI), liquides, stables au stockage et ayant un indice de couleur faible. L'invention concerne également les mélanges d'isocyanates ainsi obtenus et leur utilisation pour produire des mélanges avec d'autres isocyanates, notamment pour la production de prépolymères contenant des groupes d'isocyanates ainsi que de matières synthétiques de polyuréthane, de préférence des mousses de polyuréthane.
