    Synthesis and Characttetization of Some New Soluble Liquid-Crystalline Aromatic Polyesteamides

      摘要
    • 摘要: 从单体4,4′-对苯二甲酸酯基二苯甲酰氯制备开始,合成了三种可在N-甲基吡咯烷酮(NMP)中溶解且特性粘数较高的溶致液晶芳香聚酯酰胺。其中酰氯单体与4,4′-二氨基二苯甲烷反应生成的聚酯酰胺粘度较高,其NMP溶液25℃下的特性粘数可达1.7dl/g。这种聚酯酰胺具有交替的酯、酰胺基结构,其NMP溶液浓度为15%时在偏光显微镜下可观察到明显的液晶双折射,并且可以刮板成膜。

       

      Abstract: Starting with the synthesis of 4,4- (Terephthaloyldioxy) dibenzoyl chloride (TDC), we have got two new polyesteramides which are liquid-crysstalline and soluble in N-methyl pyrrolidone (NMP) and their properties have been characterized by Elemental analys
