Soluble polyisocyanates of isocyanurate structure are produced by heating polyisocyanates in the presence of Mannich bases and carbamic acid esters of isocyanates and secondary alcohols. When such a process is used, the polymerization reactions begin without incubation times and the catalysts need n...

Zusammenfassung:	Soluble polyisocyanates of isocyanurate structure are produced by heating polyisocyanates in the presence of Mannich bases and carbamic acid esters of isocyanates and secondary alcohols. When such a process is used, the polymerization reactions begin without incubation times and the catalysts need not be inactivated by introducing additives because they deactivate themselves at high temperatures.
