    Thermotropic Liquid Crystalline Behaviour of Ternary Unregular Aromatic-Aliphatic Polyesteramides

    • 摘要: 采用低湿溶液缩聚的方法合成了对苯二甲酰氯,二甲基联苯胺和己二醇为单体的芳酯族液晶聚酯酰胺。用DSC,X光衍射分析和偏光显微镜等手段研究了该系列聚酯酰胺的热致液晶行为,确认了二甲基联苯胺单体用量在20%(mol)的情况下,所得聚酯酰胺仍为向列型液晶聚合物。由于聚酯酰胺分子间聚酰胺链段之间的氢键作用,随着二甲基联苯胺用量增加至60mol%时,所得的聚酯酰胺己无液晶转变温度,其液晶区间即从熔融温度直至分

       

      Abstract: The aromatic-aliphatic polyesteramides were synthesized by low tempcrature solution copolycondensation of monomers, p-terephthalyl chloride(TPC),dimethylbenzidine(DMBD) and hexylene glycol(HG) in the N-methylpyrrolidone (NMP) -anhydrous lithium chloride(L
