Abstract: The invention is a process for the preparation of elastic polyurethane flexible foams having densities from approximately 25 to 60 kg/m3, and producing molded articles in closed molds at temperatures from 25 DEG to 80 DEG C., comprising reacting (A) an organic polyisocyanate prepolymer having an isocyanate content from 6 to 20 percent by weight prepared by reacting a toluene diisocyanate and/or a diphenylmethane diisocyanate with a di- to tetrafunctional polyether polyol having a hydroxyl number from 20 to 50 and oxyethylene terminal group content of at least 10 to 30 percent by weight (B) a mixture of compounds containing reactive hydrogen atoms, comprising a mixture of (a) from 55 to 89.5 parts by weight of at least one di- to tetrafunctional polyether polyol having a hydroxyl number of from 20 to 80 and less than 10 percent by weight terminal oxyethylene groups, (b) from 0.5 to 20 parts by weight of at least one alkanolamine, and (c) from 10 to 25 parts by weight water, in the presence of (C) a blowing agent, (D) a catalyst, and optionally (E) auxiliaries and/or additives.
