| 摘 要： | 本文以苯甲酸对苯二酚酯双马来酰亚胺（Ｉａ）和二苯醚二胺为单体，合成了Ｉａ／二苯醚二胺的共聚物，应用ＦＴＩＲ谱、热分析ＤＴＡ和ＤＳＣ、热台偏光显微镜对共聚物的结构和液晶行为进行了研究。该类共聚物具有较好的热致液晶行为，其液晶相结构可以通过共聚物的化学交联反应而固定在交联网络中，从而形成液晶网络材料。

| Abstract: | The liquid crystalline thermosetting copolymers based on liquid crystallinetrismalelinide(Ia ) containing ester bonds have been synthesized by 4,4'-diaminobiphenylether addition polymerization. These copolymers have exhibited thermotropic liquid crystalline behaviors in monomers and networks.The liquid crystalline characterscould be retained in crosslinked networks at curing in liquid crystailine phase by chemicalstress reaction under thermodynamlc stress field. |
