摘要
以２，５－二氯对苯二甲酰氯，ｏ－、ｍ－、ｐ－苯二酚，２，７－、２，６－、１，５－、１，６－萘二酚，１，６－己二醇为单体，溶液缩聚得到了３个系列１２种热致性液晶氯代聚芳酯，采用红外光谱（ＩＲ）ＤＳＣ／ＴＧ、Ｘ衍射、热台偏光显微镜、扫描电镜（ＳＥＭ）等对所获得的聚合物结构、液晶性、耐热性、结晶性、在观形态、溶解性进行了表征分析。较详细地探讨了热致性液晶聚芳酯侧基取代和柔性链段等不同结构与性能之间的关系。
Three series of thermotropic liquid crystalline chloro-polyesters were prepared from resorcinol, pyrocatechol, hydroquinone, 1, 5-, 1, 6-, 2, 7-, 2, 6-dihydroxynaphthalene and 2, 5-dichloroterephthaloyl dichloride.Some properties of polymers obtained were charaterized by IR DSC-TG, X-RAY diffraction,SFM and polarized hot-stage microscopy.The thermotropic liquid crystalline of chloro-polyesters contained toughened chain is better.
