Excellent flame-and smoke-retardant non-shrinkable polyurethane foam
 An excellent flame- and smoke-retardant non-shrinkable polyurethane foam is prepared by reacting a polyhydroxyl compound consisting of PA1 (A) a polyol having at least two hydroxyl groups and having a molecular weight of from 1,000 to 10,000, and PA1 (B) an aliphatic amino alcohol, the amount of which is 2.1 to 8.0 equivalents per hydroxyl group of the polyol (A) with an organic polyisocyanate in the presence of water and/or other blowing agents, catalysts and surfactants. The polyurethane foam thus obtained has high resilience together with an improved S.A.G. factor.
