摘要
探索了Ｎ，Ｎ＇－双（对羰甲氧基苯甲酰基）己撑二酰胺（ＤＥＡ）与１，６－己二醇进行酯交换、缩聚反应的催化剂，并对酯交换率和熔融缩聚反应动力学等进行了研究。通过红外光谱，Ｈ＇－ＮＭＲ．Ｃ￣（１３）－ＮＭＲ等证实了所合成的聚合物为交替结构的聚酯酰胺。经熔点、粘度、热氧化稳定性等的测定可知，所合成的交替结构聚酯酰胺（Ａ－ＰＥＡ）具有较为优良的性能。
The reaction catalysts and ratio of the ester interchange between N,N'-bis -(p- carbomethoxybenzoyl) hexamethylenediamine and hexa-1,6-diol were studied,also the kinetics of melt polycondensation.By means of IR,H'-NMR spectra and C￣(13)-NMR,it was certified that the synthesized polymer was the polyesteramide with an alternating microstructure.The properties of the polymer were studied by means of DTA, Viscosimeter,TG.It was shown that the synthesized alternating polyesteramide had better properties.
