摘　　要：介绍了在聚对苯二甲酰对苯二胺(PPTA)树脂主链骨架改变、侧基上引入取代基和超支化结构等改性方法的研究现状,评价了几种方法的改性效果。分析结果表明,主链骨架改变和侧基上引入取代基改行方法仍是目前研究的主要方向;改善PPTA树脂性能的有效方法是改变聚合物的化学结构。Remodeling the structure of polymers is an effective way to improve the properties of PPTA resin.This paper states the research progress on modification of PPTA by changing the main chain,introducing substituted parts into the branch chain and hyperbranched structures into the main chain.The effects of modification by various methods are also evaluated.The main directions of research are still the two mentioned above.

关 键 词：PPTA 共缩聚 溶解性 改性
