摘　　要：通过共缩聚及改变单体加料顺序和方法,得到了两系列共聚型聚酰亚胺,并应用FT-IR、UV、X射线衍射、TGA、机械性能测试等方法,对所得聚酰亚胺树脂的性能进行了表征.结果表明,所得共聚型聚酰亚胺树脂成膜性能良好,能够得到坚韧且具有弹性的薄膜材料,其在400～450nm区域的透过性能良好,在有机溶剂中的溶解性能显著增强,并保持了聚酰亚胺特有的良好机械性能及耐热性能.In this paper, through controlling of charging methods and orders of the monomers, two series of polyimides were synthesized by the copolycondensation. Meanwhile, the properties of the resultant polyimides were characterized by using FI-IR, UV, X-ray, TGA and measurement of mechanical properties. The results show that the resultant polyimide resins can form high quality films with excellent toughness and elasticity. The polyimide films hold good transparence from 400 - 450nm. All of the resulting polyimides exhibit well solubility in some organic solvents and still retain excellent thermal properties and mechanical properties.
