| 摘 要： | 为了改善聚酰亚胺的不溶不熔性, 一类可溶性苯并噁唑侧基聚酰亚胺树脂被成功制备. 从合成的新型二元胺单体出发, 制备了侧链为邻羟基苯胺酰胺结构的聚酰亚胺体系, 进一步催化环化邻羟基苯胺酰胺为苯并噁唑结构, 并对这两类不同结构的聚合物树脂进行了红外光谱的结构表征, 以及最终成膜的力学性能和耐热性能测试. 研究结果表明: 苯并噁唑侧基聚酰亚胺的力学性能优于相应的主链型聚酰亚胺, 且TGA分析表明, 其初始分解温度高达597 ℃, 有望用于航空航天方面高强、高模、耐高温的结构材料.

| Abstract: | A novel diamine monomer 3,5-diaminobenzoic-4'-(o-hydroxy) aniline acylamide has been synthesized,and a new polyimide(PI) containing pendent benzoxazoline group was synthesized from this diamine,3,3',4,4'-oxydiphthalic dianhydride(ODPA) and bis(4-aminophenyl)ether(ODA) by a one-step high temperature polycondensation with a certain catalyzer in 1-methyl-2-pyrrolidinone(NMP).This PI is soluble in NMP.At the same time,mechanical and thermally stable properties of the PI film were investigated.The excellent mech... |
