摘要
利用4,4′-二羟基二苯硫醚(44DHDPS)、碳酸钾和4-氯硝基苯(4CNB),在N,N-二甲基甲酰胺和甲苯的混合溶剂中回流反应,合成得到了4,4′-双(4-硝基苯氧基)二苯硫醚(DNDPS);随后,在钯/炭和水合肼体系中还原得到4,4′-双(4-氨基笨氧基)二苯硫醚(DADPS),并与2,2-双[4-(3,4-二羧基苯氧基)苯基]丙烷二酐(BPADA)进行聚合反应,脱水亚胺化,得到聚硫醚酰亚胺(PTEI)树脂。采用聚硫醚酰亚胺树脂对环氧胶粘剂进行改性,效果良好。
In the presence of potassium carbonate, the compound of 4,4＇-bis（4-nitrophenoxy）diphenylsulfide （DNDPS） was synthesized through reflux reaction between 4-chloronitrobenzene and 4,4＇-dihydroxydiphenylsulfide （44DHDPS） in the mixture solvents of N,N- dimethylformamide and toluene.The monomer of 4,4＇-bis（4-aminophenoxy）diphenylsulfide （DADPS） was also obtained through reduction reaction of DNDPS in Pd/C-hydrazine hydrate system.The polythioetherimide （PTEI） resin was further synthesized by polymerization between DADPS and 2,2-[4-（3,4-dicarboxyphenoxy）phenyl]propane dianhydride （BPADA） and dehydrate imidization reaction.The properties of the epoxy adhesive system modified with obtained PTEI resin were improved obviously.
