ABSTRACT:
Rigid and semi-rigid, fire-resisting polyurethane foams which are prepared by reacting in the presence of a foaming agent and a reaction catalyst an organic polyisocyanate and at least one polyether-polyol having the general formula: ##STR1## IN WHICH Z REPRESENTS A NUMBER BETWEEN 2 AND 6, X AND Y REPRESENT NUMBERS BETWEEN 0 AND 12 SUCH THAT THE MEAN VALUE X+Y PER CHAIN IS BETWEEN 0 AND 12, AND THAT Z (X+Y), IN WHICH X+Y REPRESENTS THE MEAN VALUE OF X+Y IN THE ENTIRE MOLECULE, IS BETWEEN 1 AND 72, AND Z represents a radical of valence z which is the residue of an organic polyhydroxyl compound initiator having from 2 and 6 hydroxyl groups.
