摘　　要：采用酯化和催化氢化的方法合成一种含有脂环结构的新型二胺单体1,4-双(4-氨基苯甲酰氧亚甲基)环己烷,并以此单体分别与两种二酐ODPA(二苯醚四羧二酐)、PMDA(均苯四酸二酐),经两步法化学环化制得聚酰亚胺.通过红外光谱表征、热失重分析、溶解性能测试探讨其结构与性能的关系.A novel diamine monomer containing alicyclic structure, 1, 4 - bis （4 - aminobenzoyoloxymethyl） eyelohexane was synthesized by esterification and catalytic hydrogenation. Then the polyimides were prepared by two-step way via chemical imidization of two dianhydride monomers： ODPA and PMDA. The relationship between structure and properties were studied through the characterization of IR, TGA ts and solubility test.
