聚酰胺酰亚胺作为重要的高性能材料应用广泛,如特种工程塑料。以L-丙氨酸和3,3’,4,4’-联苯四酸二酐为主要原料,利用以离子液体为介质的绿色合成方法制备了一种聚酰胺酰亚胺,并由正交试验得到最佳聚合条件。实验结果表明:该聚酰胺酰亚胺具有光学活性及一定的生物可降解性,良好的热稳定性,5%失重温度约367.5℃,600℃残余质量达61%,且在多种极性非质子溶剂都有较好的溶解性。 Polyamideimide is widely used as an important high-performance material, such as special engineering plastics. A polyamideimide was prepared by using L-alanine and 3,3 ’, 4,4’-biphenyl tetracarboxylic dianhydride as the main raw materials, using a green synthesis method using ionic liquid as a medium, To test the best polymerization conditions. The experimental results show that the polyamideimide has optical activity and certain biodegradability, good thermal stability, the temperature of 5% weight loss is about 367.5 ℃, the residual mass of the polyamide is 61% at 600 ℃, Proton solvents have better solubility.
