PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam the yellowing of which caused by nitrogen oxide (NO<SB>X</SB>) is reduced. SOLUTION: The hardly yellowed flexible polyurethane foam is obtained by reacting a polyol with an organic polyisocyanate in the presence of a foaming agent, a foam stabilizer, a catalyst and an additive, and contains 0.5-7.0 pts. mass tetraphenyldipropylene glycol diphosphite as the additive based on 100 pts. mass polyol formulated therewith. The molded product for clothes, sanitary uses or cosmetics is obtained by molding the hardly yellowed flexible polyurethane foam. The hardly yellowed flexible polyurethane foam is economically and effectively prevented from the yellowing caused by the NO<SB>X</SB>. COPYRIGHT: (C)2006,JPO&NCIPI |
