摘　　要：采用固体超强酸催化剂(磷钨酸,H_3O_(40)PW_(12)·x H_2O),以亚磷酸二乙酯、二乙醇胺和丙酮为原料合成含N和P反应型阻燃剂N,N-双(2-羟乙基)氨基异丙基膦酸二乙酯(BHAIPE),并探讨了反应机理。通过FT-IR、~1H-NMR、^(31)P-NMR对产物的表征表明,所合成的阻燃剂具有预期结构。用不同含量的该阻燃剂与4,4'-二苯基甲烷二异氰酸酯(MDI)、己二酸系聚酯二醇制备聚酯型聚氨酯弹性体(PUE),结果表明,随着阻燃剂含量增加,PUE的热稳定性和阻燃性都得到提高。The reactive flame retardant contains N and P[diethyl bis（2-hydroxyethyl） amino isopropyl phos-phonate ]was synthesized from diethyl phosphite,diethanolamine and acetone with solid superacid （ phosphotungstic acid, H3O40PWI2 · xH2O） as the catalyst,and the reaction mechanism was explored. The characterization of the product showed that the synthesized flame retardant has the expected structure by FT-1R, 1H-NMR and 31P-NMR. Then PU elastomer was prepared by different levels of the flame retardant with MD1 and aliphatic polyester diol. Thermal stability and flame resistance of PUE were improved with the content of flame retardant increased.
