本文利用对苯二甲酰氯（ＴＰＣ），对苯二胺（ＰＰＤ）和亚甲基数为２和６的两种脂肪族二元胺（ＡＤＡ）合成了具有不同序列结构的芳香一脂肪族共聚酰胺．研究了共聚酰胺的序列结构参数──无规度Ｂ和数均序列长度Ｌｎ与液晶临界浓度Ｃ＊和中介相的类型之间的关系．
In this paper, aromatic-aliphatic copolyesters with different sequence structures were synthesized using terephthalic acid chloride (TPC), p-phenylenediamine (PPD) and two kinds of aliphatic diamines (ADA) Amide. The sequence structure parameters of copolyamide - the relationship between the randomness B and number average sequence length Ln and the type of liquid crystal critical concentration C * and the type of mesophase were investigated.
