摘　　要：利用含有醚、酮及砜基官能团的二胺、二酐单体通过二步法合成了几种不同结构的聚酰亚胺。并应用FT-IR、TGA、DSC、X-Ray等测试方法,对所得聚酰亚胺树脂的性能进行测试与比较。结果表明,不同官能团对聚酰亚胺的性能影响极为不同,醚酮类聚酰亚胺能够在保持其热性能的前提下在一定程度上改善其溶解性,而含砜基聚酰亚胺则能极大地改善溶解性。应当根据具体应用对聚酰亚胺的种类进行选择。In this paper, through two-step method different polyimides with ether, ketone,and sulphone groups were synthesized. Meanwhile, the property comparision of the resultant polyimides was characterized by FR-IR,TGA, DSC, X-Ray and so on. The result showed that different groups have different effects to the resultant PI. PI with ketone and ether groups can improve solubility to some extent and retain PI＇s heat-resistance,while PI with sulphone group can improve solubility greatly. The application of PI with different group should be in accordance with their practical requirement.
