摘要：介绍了含介生基团的三个环亚胺醚通过柔性间隔剂连接到杂环单元的合成方法。阳离子开环异构化聚合将两者，即2-（4-（4-甲氧基-4′-联苯氧基）丁基）-2-恶唑啉（meobiphh -4- oxz）和2-（6-（4-甲氧基-4′-联苯氧基）己基）-2-恶唑啉（meobiphh -6- oxz）提供了热致液晶（LC）聚（n -酰基亚胺）s，而2-（4-（4-苯基苯氧基）丁基）-2-恶唑啉（BiPh-4-Oxz）聚合得到结晶聚合物。
Abstract : The synthesis of three cyclic imino ethers containing mesogenic groups attached to the heterocyclic unit through flexible spacers described. Cationic ring opening isomerization polymerization of the two of them, i.e., 2-(4-(4-meth-oxy-4'-biphenyloxy)butyl)-2-oxazoline (MeOBiph-4-Oxz) and 2-(6-(4-methoxy-4'-bi-phenyloxy)hexyl)-2-oxazoline (MeOBiPh-6-Oxz) provided thermotropic liquid crystalline (LC) poly(N-acylethylene-imine)s, while the polymerization of 2-(4-(4-phenylphenoxy) butyl)-2-oxazoline (BiPh-4-Oxz) led to a crystalline polymer.
