    Abstract: The present invention relates to polyisocyanates containing tertiary nitrogen with an (average) NCO functionality of 2.3 to 4.3 which, despite the presence of tertiary nitrogen and isocyanate groups in the same molecule, would be stable in storage, could be dissolved or dispersed in water without difficulty, optionally after at least partial alkylation or protonation, and would be suitable as starting components in the production of polyurethane plastics and, above all, as crosslinking agents for water-containing binders or binder components.

    Abstract: Diisocyanates corresponding to the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 (an isocyanate-containing radical) are as defined herein are made by several processes. These diisocyanates may be made by phosgenating the diamine in which the diisocyanate is based. They may also be produced by treating the bis-urethane of the tertiary alcohol corresponding to the diisocyanate with phosgene. Such diisocyanates may also be made by treating a specific type of bis-urea with hydrogen chloride. The diisocyanates corresponding to the above-given formula are particularly useful in the production of polyurethanes having good flame-proof and mechanical properties.
