摘　　要：N-溴代丁二酰亚胺(NBS)与聚苯醚(PPO)进行溴化反应,合成了溴化率为15%的溴化聚苯醚(BPPO).BPPO再与4-羟基查尔酮(4-HC)反应合成了光敏性聚苯醚(PPPO),并通过UV光照射合成了光交联型聚苯醚(cPPO),利用1HNMR,FT-IR,UV-Vis,TG和拉力测试对聚合物结构和性能进行表征.结果表明:光交联可提高聚苯醚的耐溶解性和机械性能.Polyphenylene oxide(BPPO)with a bromination ratio of 15%was prepared by the reaction of polyphenylene oxide(PPO)with N-bromosuccinimide(NBS),and a photosensitive polyphenylene oxide(PPPO)was synthesized by the reaction between BPPO and 4-hydroxy chalcone(4-HC).After UV irradiation,photocrosslinked polyphenylene ether(cPPO)was produced,and the chemical structures and the properties of the polymers were investigated by 1H NMR,FT-IR,UV-Vis,TG and tensile testing.The results showed that photocrosslinking could improve the solvent resistance and mechanical properties of the polyphenylene ether.
