以甲苯二异氰酸酯和聚酯多元醇为基料的软质聚氨酯泡沫塑料在160°C下用膦酸二甲酯（CH_3 O）_2 P（O）H或膦酸二乙酯（C_2 H_5 O）_2 P（O）H液化。通过1H、13 C和31 P核磁共振（NMR）光谱研究了降解产物。提出了可能的反应机理。© 2000约翰威利父子公司应用聚合物科学杂志78：2565-2573，2000
Flexible polyurethane foam based on toluene diisocyanate and polyester polyol has been liquefied by treatment with either dimethyl phosphonate (CH3O)2P(O)H or diethyl phosphonate (C2H5O)2P(O)H at 160°C. The product degraded has been studies by 1H, 13C, and 31P nuclear magnetic resonance (NMR) spectroscopy. The likely reaction mechanism is presented. © 2000 John Wiley & Sons, Inc.
