Summary:PURPOSE:To provide a method for producing an uniform polyurethane foam without causing troubles such as public hazards and environmental pollutions, while avoiding the generation of scorches. CONSTITUTION:A method for producing a polyurethane foam is characterized by reacting an organic polyisocyanate with a polyol and an aliphatic monohydric alcohol-alkylene oxide adduct having a hydroxyl value of >=150mgKOH/g or an aromatic monohydric alcohol-alkylene oxide adduct having a hydroxyl value of >=170mgKOH/g.
