The invention relates to a process for the production of polyurethane foams by reacting a) at least one organic polyisocyanate with b) at least one polyalkylene-polyol (b1) having a hydroxyl number of from 30 to 500, obtainable by alkoxylation of at least one initiator molecule from the group consisting of N,N'-bis(3-aminopropyl)ethylenediamine, tripropylenetetramine and tetrapropylenepentamine using at least one alkylene oxide, preferably ethylene oxide and/or 1,2-propylene oxide, or mixtures of the polyoxyalkylene polyols (b1) and other polyhydroxyl compounds having a functionality of from 2 to 8 and a hydroxyl number of from 15 to 500, and c) if desired, chain extenders and/or crosslinking agents, in the presence of d) blowing agents and, if desired, e) catalysts and f) additives, and to the novel polyoxyalkylene-polyols (b1) which can be used for this purpose.
