PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane foam that overcomes problems of the prior art, does not require the use of a physical foaming agent, does not emit a foul odor or the like, does not discolor or deteriorate a material, such as polyvinyl chloride and ABS resin, that is placed in contact with the polyurethane foam, and can be foamed in situ by a spray foamer or the like. SOLUTION: This method of producing a polyurethane foam is to react a polyol component containing a benzilic ether phenol resin having a hydroxymethyl group with an organic polyisocyanate component in the presence of an organotin urethanizing catalyst, a tertiary amine urethanizing catalyst having a functional group reactive with an isocyanate in the molecule, and water. |
