摘要
在以N,N二甲基乙酰胺为溶剂,三乙胺为酸吸收剂的条件下,将自制的反式-4,4′-偶氮苯二甲酰氯与对苯二胺进行低温缩聚反应,合成了1种新型的反式偶氮苯聚芳酰胺。用红外光谱、示差热扫描量热分析,热重分析,偏光显微镜,紫外光谱对其结构及性能进行了表征。合成的聚合物表现出了一定的结晶性能,聚合物的稀溶液呈现出溶致液晶行为。
A new kind of azobenzene modified polyamide was prepared by the low temperature polycondensation of trans-azobenzene-4,4'-dicarbonyl chloride with para-phenylene diamine. The polymer was characterized by IR, DSC, TG, UV and Polarized optical microscopy. The results showed that the polymer exhibited crystalline phase, the Azo-PA solution formed liquid crystalline structure (i. e. lyotropic) in DMAC.
