【摘要】 利用Ｓｃｈｏｔｔｅｎ－Ｂａｕｍａｎｎ反应合成了规则链芳－脂族聚酯酰胺系列化合物及相应的模型化合物，着重研究了聚合物的结构与液晶性的关系。结果表明这种结构的聚酯酰胺为结晶性聚合物，熔体呈向列型液晶态；聚合物的熔点主要取决于聚合物的结构，即酯、酰肢健的位置、芳环取代方式和脂肪链的长短。更多还原

【Abstract】 Two series of polyesteramides with regular aromatic-aliphatic chain structure and their related model compounds were synthesised by Schotten-Baumann reaction.The relationship between the chemincal structure and liquid crystalline properties of polyesteramides was emphatically investigated.The results show that they are crystalline polymers and form nematic mesophase.The melting points of polyesteramides depend on the position of ester and amide groups in the rigid red like structure,the regularity of molecular structure,and the flexiblizing spacer bonding the rigid units.更多还原
