| titleOfInvention | Urea groups-containing diisocyanates, optionally dissolved in NCO-prepolymers, a process for preparing same as well as their use in the production of polyurethane resins |
| abstract | m = 0 oder eine ganze oder gebrochene Zahl von 0 bis 3, R 1 = Wasserstoff, eine Alkylgruppe mit 1 bis 4 C-Atomen, R 2 = einen, gegebenenfalls substituierten Phenylenrest durch Umsetzung von Thioäthergruppen aufweisenden Diisocyanaten mit 0,4 bis 0,8 Mol Wasser pro Mol Diisocyanat und gegebenenfalls anschließendes Lösen des entstehenden, Harnstoffgruppen aufweisenden Diisocyanats in einem NCO-Präpolymeren der genannten Art; sowie die Verwendung der Diisocyanate bzw. ihrer Lösungen als Aufbaukomponente bei der Herstellung von Polyurethankunststoffen.n oder einen aliphatischen Kohlenwasserstoffrest mit 2-12 C-Atomen, wobei zwischen dem Stickstoffatom und dem Schwefelatom mindestens 2 C-Atome angeordnet sind. The application relates to new diisocyanates of the formula (I) which are liquid at room temperature or which can be liquefied by heating to a maximum of 80 ° C and which contain thioether groups and urea groups and which may be in the form of prepolymers which are liquid at room temperature or can be liquefied by heating to a maximum of 80 ° C Polyhydroxyl compounds and organic diisocyanates are present; a process for the preparation of these diisocyanates or solutions In the formula: m = 0 or an integer or fraction from 0 to 3, R 1 = hydrogen, an alkyl group with 1 to 4 carbon atoms, R 2 = an optionally substituted phenylene radical by reacting diisocyanates containing thioether groups with 0.4 to 0.8 moles of water per mole of diisocyanate and, if appropriate, then subsequently dissolving the resulting diisocyanate containing urea groups in an NCO prepolymer of the type mentioned; and the use of the diisocyanates or their solutions as structural components in the production of polyurethane plastics. or an aliphatic hydrocarbon radical with 2-12 C atoms, at least 2 C atoms being arranged between the nitrogen atom and the sulfur atom. |
