Polyisocyanates, preparation and use thereof |
| abstract |
ABSTRACT OF THE DISCLOSURE The present invention related to a process for the production of specific polyisocyanates by reacting di-amines containing hydrogen atoms which are active in the context of the isocyanate addition reaction with excess quantities of organic diisocyanates The invention also relates to a modification of the above process charac-terized in that the diamines are reacted first with excess quantities of a first diisocyanate after which the thus obtained reaction product which contains a urea group and a biuret group is reacted in a second stage with a second diisocyanate. The invention also related to the use of polyisocyanates as the isocyanate component in the production of polyurethane plastics by the isocyanate-polyaddition process. |
