Abstract: Self-extinguishing urethane group containing polyisocyanurate foams are prepared by reacting a polyisocyanate with a polyesterol obtained by condensing an aliphatic dicarboxylic acid with a mixture of an aliphatic diol and N,N'-bis-(ethanol-2)-diaminooctachlorodiphenyl.

Abstract: 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.
