摘要： 将聚苯醚硝化、还原,分别合成了硝化聚苯醚和胺化聚苯醚,最高硝基、氨基取代度分别为95%、65%.讨论了各种反应条件对取代度的影响,并对修饰改性的聚苯醚进行了表征。

关键词: 聚苯醚, 胺化, 硝化, 取代度

Abstract: The chemical modification of poly(2,6-dimethyl-1,4-phenylene oxide)(PPO) has been carried out by incorporating nitro or amino groups in the PPO backbone. The obtained maximum monosubstitution value is 95% or 65% respectively. The effects of reaction conditions on the functional group contents in PPO were discussed. The modified PPO obtained was characterized by FT-IR、1H NMR spectroscopy, nitrogen analysis, solubility test and X-ray diffraction study.

Key words: poly(phenylene oxide), amination, nitration, substitution value
