摘　　要：介绍了40多年来国内外开发的高性能热塑性聚酰亚胺(Ployimide,简称PI)树脂的主要品种,如Vespel,Torlon,Ultem,Aurum等。如何使得这类材料同时具有优异的综合性能和熔融加工性是人们的研究焦点。本文还介绍了GE公司新近报道的新品种Extem和最近引起国内外同行关注的异构聚酰亚胺树脂。异构的聚酰亚胺是近几年新兴起的结构材料之一,与传统结构的聚酰亚胺比较,具有更高的玻璃化温度,良好的溶解性能,低的熔融粘度,宽的加工窗口,和相当的机械性能和热稳定性,是一种较有发展前景的结构材料。High performance thermoplastic poiyimide （PI） resins, such as Vespel , Toflon , Ultem , and Aurum , developed over last forty years have been reviewed. It is the major interest to develop PI resins with good melt processability while keeping an advantageous combination Of properties. The newly developed Extem esins and recently reported isomeric polyimides have been specifically introduced. Compared with conventional PIs, isomeric polyimides with higher Tg and solubility, lower melt viscosity, wider processing window, as well as comparable mechanical property and thermo-oxidative stability will be noted in the future.
