Abstract: The invention relates to s-triazine radical-containing polyether polyol mixtures having functionalities of from 2 to 6 and hydroxyl numbers of from 210 to 640, prepared by the oxyalkylation of a mixture of one or more polyamino-1,3,5-triazines, preferably melamine, and an alkanol having a hydroxyl functionality of from 2 to 6 and having 2 to 18 carbon atoms, water, or their mixtures, in the absence of catalysts and conventional inert polar solvents. The resulting polyether polyol mixtures are suitable for the preparation of rigid polyurethane, polyisocyanurate, and urethane group-containing polyisocyanuate foams produced by means of the polyisocyanate polyaddition process.

Abstract: A process is disclosed for producing a polyisocyanate containing biuret groups from at least one aliphatic, cycloaliphatic or araliphatic diisocyanate or a mixture of two or more such substances, and from at least one amine or water or a mixture of water and at least one amine as reactants. The reactants are mixed together and made to react in a mixing element with a high shearing effect.

Abstract: A process for producing polyisocyanates containing one or more biuret groups, by reacting a) an aliphatic or cycloaliphatic isocyanate with several isocyanate groups (isocyanate a) with b) a tertiary alcohol or a mixture of water and a tertiary alcohol (biuretting agent b) at reaction temperature of 100 to 250 DEG C, said process being characterized in that the reaction is conducted in the presence of c) a stabiliser (c) in which there are catalytic quantities of urea, ammonia, biuret, a urea derivative of the formula (I), in which R , R , R and R are hydrogen, C1-C10 alkyl or C5-C10 aryl, or a carbonic acid amide of formula (II) in which R is C1-C12 alkyl group, in which 1, 2 or 3 hydrogen atoms may be replaced by a (III) radical.
