对近30年芳香族尼龙合成领域申请的中国专利进行了检索和统计，从化学结构、地区分布和申请单位角度总结了专利申请现状，按合成方法对专利技术进行分类讨论。低温溶液缩聚法反应条件温和，但是需采用有机溶剂，成本较高。界面缩聚法反应温度较低，但溶剂消耗量大，需要采用高反应性能的单体。水相溶液缩聚法原料价廉，缩聚过程的升温程序多样，常采用间歇聚合工艺，应用较为广泛。直接熔融缩聚法不用溶剂，压力较低，但是只适用于较易熔融的单体原料。通过本文分析得出，原料中含对苯二甲酸的芳香族尼龙是得到较为深入研究的芳香族尼龙品种，水相溶液缩聚法是最适合工业化的合成方法，未来有望在这些方面取得一定工业化应用成果。%The Chinese patents in the field of aromatic polyamide’s synthesis were reviewed. We summarized the existing patents based on the chemical structure,regional distribution and application affiliation,respectively. We also made a discussion of the patents based on the synthesis method. The reaction condition of polycondensation at low temperature is easy to achieve,but it needs organic solvent and therefore increases the cost. The temperature of interface polycondensation method is low, but it consumes large amount of solvent,and needs high reactive monomers. The raw materials of aqueous phase polycondensation is cheap,and has various temperature rise programming. It often uses batch operation and is widely applied in many aromatic nylon’s synthesis. Direct melt polycondensation requires no solvent,and reacts in low pressure. But it can only be applied to monomers that is easy to melt. We conclude that the aromatic nylons with terephthalic acid as raw material have been studied extensively,while the aqueous phase polycondensation is the most suitable method for industrialization. It is expected to achieve some industrial applications in these areas in future.
