    摘要: Disclosed is a method for producing a flexible polyurethane foam which has a higher biomass content compared to a conventional flexible polyurethane foam and also has good foam properties and appearance. The method is characterized by using a polymer-dispersed polyol produced by the polymerization of a vinyl monomer in the presence of a polyol (a1) derived from a natural oil-and-fat and/or a polyoxyalkylene polyol (a2): the polyol (a1) derived from a natural oil-and-fat: a polyol (a1) derived from a natural oil-and-fat, which is produced by attaching a hydroxy group to a natural oil-and-fat through a chemical reaction and has a hydroxy value of 20 to 250 mgKOH/g and a molecular weight distribution of 1.2 or more; and the polyoxyalkylene polyol (a2): a polyoxyalkylene polyol produced by the ring-opening polymerization of the polyol (a1) and an alkylene oxide (c) in the presence of at least one polymerization catalyst (b) selected from the group consisting of a coordinate anionic polymerization catalyst and a cationic polymerization catalyst.
