摘　　要：制备了两个系列的全芳香族共聚酯类热致液晶。对所得聚合物作了红外、偏光显微镜及差热分析，并测定了各聚合物的熔融指数。结果显示，所制备的聚合物为热致向列型液晶聚合物。Two series of title polymers were prepared.By using IR,polarized light mi-croscope and DTA,their structure and properties were identified.Their melt index were alsobe determined. The results showed that all polymers prepared were thermotropic liquid cryrt-ailine polymers and formed nematic phase only.

关 键 词：液晶 制备 热致液晶 高聚物
