| 摘要 |
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.
