| titleOfInvention | Method for producing flexible polyurethane foam |
| abstract | Provided is a method for producing a flexible polyurethane foam, in which a flexible polyurethane foam having a good cushioning property can be satisfactorily formed using a raw material derived from natural fats and oils. A polyoxyalkylene polyol (A) containing a first polyoxyalkylene polyol (A1) produced by ring-opening polymerization of an alkylene oxide (c) to a polymerization initiator (b) in the presence of a polymerization catalyst (a); And a step of reacting the polyisocyanate compound (B) in the presence of the catalyst (C) and the foaming agent (D). The polymerization catalyst (a) is at least one selected from the group consisting of a coordination anion polymerization catalyst and a cationic polymerization catalyst, and the polymerization initiator (b) is formed by adding a hydroxyl group to natural fats and oils using a chemical reaction. A polyol derived from natural fats and oils having a hydroxyl value of 20 to 250 mgKOH / g and a ratio (Mw / Mn) of mass average molecular weight to polystyrene-reduced number average molecular weight of 1.2 or more. |
