Zusammenfassung:	本发明涉及异佛尔酮二异氰酸酯二聚的新方法，还涉及按所述方法制备的脲二酮多异氰酸酯作为聚氨酯塑料的原料组分，特别是作为异氰酸酯组分以制备交联的脲二酮粉末喷漆交联剂的应用。 The invention relates to a method of preparing a polyisocyanate with at least one uretdione group by oligomerizing part of the isocyanate groups of isophorone diisocyanate in the presence of a catalyst which accelerates the dimerization of isocyanate groups, wherein the oligomerization catalyst comprises a saline compound comprising from 10 to 100 wt. % of 1,2,3- and/or 1,2,4-triazolate structures (calculated as C2N3; molecular weight=66) in the anion, and the products prepared by this method.
