摘　　要：以铜-胺为催化剂、氧气为氧化剂,2,6-二甲基苯酚(DMP)和2,2’,4,4’-四甲基双酚A(TMBPA)发生氧化偶联共聚反应合成端羟基聚苯醚。考察了单体配比、铜-胺催化剂的组成和种类等对聚合反应时间和双端羟基聚苯醚收率的影响。进而通过端羟基的醚化反应对端羟基聚苯醚进行衍生。通过红外光谱和核磁氢谱,分析了双端羟基聚苯醚衍生前后的结构变化。Hydroxyl-terminated polyphenylene ether was synthesized by oxidative coupling copolymerization of 2,6-dimethylphenol(DMP)and 2,2’,4,4’-tetramethylbisphenol A(TMBPA),using copper-amine as catalyst and oxygen as oxidant.The effects of monomer ratio,composition and type of copper-amine catalyst on polymerization reaction time and yield of hydroxyl-terminated polyphenylene ether were investigated.Subsequently,hydroxyl terminated polyphenylene ether was derived through the etherification reaction of hydroxyl groups.The structural changes before and after derivatization of hydroxyl-terminated polyphenylene ether were analyzed by infrared spectroscopy(FT-IR)and nuclear magnetic resonance spectroscopy(1H NMR).
