摘　　要：聚酰亚胺纤维由于其优良的性能,已成为高技术纤维领域的研究热点之一。本文归纳了聚酰亚胺纤维的聚合单体,主要有二酐单体(均苯四甲酸酐、联苯四甲酸酐、二苯醚四酸二酐、二苯酮四酸二酐等)和二胺单体(二氨基二苯醚、对苯二胺、间苯二胺等)。另外,还有第三单体,如嘧啶环二胺、氯化对苯二胺、二氨基二苯醚等,综述了聚酰亚胺纤维的主要纺丝工艺(如干法纺丝、湿法纺丝、干湿法纺丝、静电纺丝、熔融纺丝、液晶纺丝)及其研究进展,并提出了目前聚酰亚胺纤维研发中存在的主要问题。Polyimide fiber has become one of the hot topics in the field of hi-tech fibers for its good property. Polymer monomer including dianhydrides （PMDA, BPDA, ODPA, BTDA, etc）, diamines （ODA,PPD, MPD, etc） and the third monomers（PRM,Cl-PPD, ODA etc） were reviewed in this article. The main spinning technology of polyimide fibers（such as dry spinning,wet spinning, dry-wet spinning, electro-spinning, meltspinning and liquid crystal spinning） and its research progress were summarized. Meanwhile,major problems of polyimide fibers research at present were discussed.
