Manufacturing method of flexible polyurethane foam |
| abstract |
Provided is a method for producing a flexible polyurethane foam that can be molded into a flexible polyurethane foam having good cushioning properties using a raw material derived from a natural fat or oil. A polyoxyalkylene polyol (A) containing a first polyoxyalkylene polyol (A1) produced by ring-opening polymerization of an alkylene oxide (c) in a polymerization initiator (b) in the presence of a polymerization catalyst (a), It has a process of making a polyisocyanate compound (B) react in presence of a catalyst (C) and a blowing 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 applying a hydroxyl group to a natural fat or oil using a chemical reaction, A hydroxyl value is 20-250 mgKOH / g, and the polyol-derived polyol whose ratio (Mw / Mn) of the mass mean molecular weight with respect to the number average molecular weight of polystyrene conversion is 1.2 or more. |
