FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing polyurethane foam, polyurethane foam obtained using said method and a moulded article containing polyurethane foam. In the method of producing polyurethane foam, polyol polyether and polyisocyanate react in the presence of a foaming agent, metals contained in a metal cyanide complex-based composite catalyst in amount of 1-30 ppmw per million parts of the polyol polyether and a compound which is a phophoric acid, which consists of a phosphoric acid selected from orthophosphoric acid, polyphosphoric acid and polymetaphosphoric acid and/or a partial ester similar to phosphoric acid, in amount of 0.5-100 ppmw per million parts of the polyol polyether.
EFFECT: obtaining polyurethane foam having improved pore opening.
