    摘要: Stable, liquid, homogeneous solutions of isocyanurate-polyisocyanates containing amide and/or acylurea groups in monomeric diisocyanates and/or polyisocyanates which are free from amide, acylurea and/or isocyanurate groups, are obtained by reacting polybasic carboxylic acids with diisocyanates and/or polyisocyanates to give diisocyanates and/or polyisocyanates containing amide groups and/or acylurea groups, converting the diisocyanates and/or polyisocyanates containing amide and/or acylurea groups by trimerization and, optionally, polymerization, into isocyanurate-polyisocyanates containing amide and/or acylurea groups, and mixing the products with monomeric diisocyanates and/or polyisocyanates.
