PROBLEM TO BE SOLVED: To provide a method for producing a soft foam of which hardening and curing properties in producing the soft foam are good, and having a good mechanical and a high endurance without shrinkage. SOLUTION: This method for producing the soft polyurethane foam is provided by using a polymer-dispersed polyol obtained by employing (A) a polyol synthesized by using a compounded metal cyanide complex catalyst and having a random additional structure of ethylene oxide and a >=3C alkylene oxide until its terminals, and (B) a polyol synthesized by using an alkali metal catalyst and containing >=85% primary hydroxyl groups at the terminals of its molecule, as a matrix. |
