Abstract (en)

[origin: WO03014190A1] The invention relates to a method for the production of polyurethane soft foam materials by reacting: a) polyisocyanates with b) compounds having at least two reactive hydrogen atoms with isocyanate groups in the presence of c) expanding agents. The invention is characterized in that at least one polyether alcohol, which can be produced by reacting alkylene oxides with H-functional starting substances in the presence of DMC catalysts and has a DMC catalyst content ranging between 0.1 to 1000 ppm, in relation to the weight of the polyether alcohol, is used as compounds having at least two reactive hydrogen atoms b) with isocyanate groups.
