摘　　要：对位聚芳酰胺具有优异的力学性能,但其加工困难,需溶解在浓硫酸中进行纺丝。在其大分子链引入取代基团改变了对位聚芳酰胺在有机溶剂中的溶解性,因此是改善其加工性的重要方法。本文综述了关于含取代基团对位聚芳酰胺的制备方法和溶液性质的研究进展,并介绍了多种含取代基团的对位聚芳酰胺在复合材料和功能材料领域中的应用。Para-aramids have great mechanical properties,but their processing is difficult,which need to be dissolved in concentrated sulfuric acid for spinning.Attaching substituents to the macromolecular chains of para-aramids can improve their solubility in organic solvents.Therefore,it is an effective way to improve their processability.Recent research progress on the preparation and solution properties of various substituents containing para-aramids is reviewed in this article,and the applications of the substituted para-aramids in the fields of composites and functional materials are introduced.
