    摘要： Polyisocyanates with biuret structures are produced at temperatures above 250.degree. C. More specifically, an excess of a diisocyanate having aliphatically and/or cycloaliphatically bound isocyanate groups is reacted with a diamine containing aliphatically and/or cycloaliphatically bound amino groups at temperatures above 250.degree. C. for relatively brief periods of time. Water and/or polyvalent alcohols may optionally be included in the reaction mixture. The polyisocyanates with biuret structures produced by this process are characterized by good color, good dilutability with covalent solvents and comparatively low viscosity.

    摘要： The present invention is directed to a process for the production of polyisocyanates containing isocyanurate groups by trimerizing a mixture of aliphatic-cycloaliphatic diisocyanates having a sterically unhindered isocyanate group bound to a primary aliphatic carbon atom and a sterically hindered isocyanate group bound to a tertiary carbon atom which forms a part of a cycloaliphatic ring system and 1,6-diisocyanatohexane. The present invention is also directed to the polyisocyanates containing isocyanurate groups produced according to this process and to their use, optionally in blocked form, as an isocyanate component in the production of polyisocyanate polyaddition products, preferably polyurethane lacquers.
