Abstract

Procedure for obtaining combustion-resistant urethane-foamed materials, characterized in that polyisocyanates, polyhydroxy compounds with a molecular weight of between 100 and 10,000 water and/or other blowing agents, catalysts and, if necessary, further auxiliary agents are reacted, said polyisocyanates being solutions of from 2 to 60, preferably from 5 to 50% by weight of distillation residues as obtained in the distillation of the phosgenization products of 2,4- and/or 2,6 -toluylenediamine, preferably from the mixtures of industrially obtained toluenediamine isomers in 2,4- and/or 2,6-toluenediisocyanate, especially from the mixtures of distilled industrially obtained toluenediisocyanates, having been reacted, of the free NCO groups existing in the solution from 1 to 45, preferably from 5 to 25% by weight in a form known per se to biuret groups.
