Abstract

Process for the preparation of hardly inflammable polyurethanes by condensation of at least one polyol with equivalent amounts of at least one organic isocyanate compound, optionally in the presence of activators, expansion agents and/or cell regulators, characterized in that as a polyol) a compound of the general formula (I) is used **(See formula)** in which a = 1 or 0 and 1; n = 0 to 4; R1 means at least one halogenated hydrocarbon radical as well as at least one hydroxyl-containing radical of the general formula (II) **(See formula)** and R2 means a radical of the general formula (III) **(See formula)** in which in formulas (II) and (III), R3 or R4 are a hydrogen atom or a hydrocarbon radical optionally substituted by halogen with 1 to 6 carbon atoms and m is a number from 1 to 10, preferably from 1 to 4 ; or b) a mixture of the compound of the general formula (I) and a polyol known per se is used.
