简介了半芳香聚酰胺的几种常用合成工艺,综述了均聚半芳香聚酰胺和共聚聚酰胺两个方向的合成研究现状,列举了几种典型的均聚和共聚半芳香聚酰胺的性能和应用方向。指出新品种半芳香聚酰胺的开发主要以在现有半芳香聚酰胺的基础上二元或多元共聚、填料增强的方法获得目标产品为主,以合成新型的均聚半芳香聚酰胺为辅;同时指出新型芳杂环二羧酸或芳杂环二胺是合成新型聚酰胺有价值的原料单体之一。
In this paper, several common synthetic processes of semi-aromatic polyamides are introduced. The current research on the synthesis of semi-aromatic polyamides and copolyamides are reviewed. The properties of several typical homopolymers and copolymeric semi-aromatic polyamides are summarized. Application direction. It is pointed out that the development of the new semi - aromatic polyamide is mainly based on the existing semi - aromatic polyamides based on binary or multi - component copolymerization and filler enhancement. The target products are mainly synthesized by the new semi - aromatic polyamides. At the same time, it is pointed out that the novel aromatic heterocyclic dicarboxylic acids or aromatic heterocyclic diamines are one of the valuable raw material monomers for synthesizing novel polyamides.
