摘　　要：综述了近年来几种已商品化的半芳香族尼龙(PPA),特别是聚对苯二甲酰己二胺、聚对苯二甲酰壬二胺、聚对苯二甲酰癸二胺、聚己二酰间苯二甲胺的结构、性能、改性及加工应用等;介绍了一种改善PPA加工性能的方法,即添加少量热致液晶高分子可改善PPA的加工性能,同时可保持其良好的力学性能;总结了PPA的应用领域,综述了国内PPA的研究水平,并指出了PPA的主要研究方向。Semi-aromatic nylons as a kind of high performance engineering plastics have high temperature resistance, high strength, resistance to chemical corrosion and good dimensional stability. The structure, performances, modification and applications of several commercialized semi-aromatic nylons including poly （hexamethylene terephthalamide）, poly （nonamethylene terephthalamide）, poly （decamethylene terephthalamide） and poly （m-xylylene adipamide） were summarized. A method for the improvement of the processability of the semi-aromatic nylons was introduced. A small amount of thermotropic liquid crystal polymer can improve the proeessability of the semi-aromatic nylons effectively, and at the same time their good mechanical properties are kept. The main applications of the semi-aromatic nylons were discussed. The current domestic researches for the semi-aromatic nylons were reviewed and the development trends were discussed. E
