    摘要： A process for producing a flexible polyurethane foam excellent in mechanical strength, and exhibiting reduced shrinkage. The foam is produced using a polyol (A) containing from 40 to 100 mass % of a polyoxyalkylene polyol (A1). The polyoxyalkylene polyol (A1) is produced through an initial step of adding, to a reaction liquid containing an initiator and a double metal cyanide complex catalyst, 5 to 20 mass % of an alkylene oxide, based on the content of the initiator. After the initial step, an alkylene oxide is newly supplied to carry out polymerization. In the initial step, the temperature of the reaction system when addition of the alkylene oxide is started is from 120 to 165° C., and the maximum temperature of the reaction system after the alkylene oxide has been added in the initial step is higher by 15 to 50° C. than the temperature when addition of the alkylene oxide was started.
