摘要： A method for producing a flexible polyurethane foam by the reaction of an active-hydrogen-containing component composed of an active hydrogen compound, a blowing agent, and an additive with an organic polyisocyanate compound: said blowing agent being carbon dioxide which is generated by the reaction of water with free isocyanate groups, said organic polyisocyanate compound being a mixture of diphenylmethane diisocyanates and polyphenylmethane polyisocyanate, which the mixture contains said diphenylmethane diisocyanate and said polyphenylmethane polyisocyanate in a mixing ratio of not more than 1.0 and 4,4'-MDI in a ratio of not more than 60% by weight based on the whole isocyanate mixture, and said polyphenylmethane polyisocyanate having an average functionality (hereinafter referred to as "f") of not less than 2.9 and containing diphenylmethane diisocyanate in an amount of less than 35% by weight.
