摘　　要：通过合成的4-（4’-辛氧基-苯甲酰氧基-4-苯甲酰氧基）-苯基丙烯酸酯与苯乙烯在一定条件下聚合得到一种聚合物。采用广角X-射线衍射仪、热重分析仪和差示扫描量热计表征了合成聚合物的结构及热性能。该液晶聚合物为固定液制成色谱柱，对几组混和物进行分离，效果良好。该液晶聚合物固定液使用温度为100-220℃。Under certain conditions a polymer was polymeirized by synthesized 4 - （4＇ - octoxy - benzoxy -4 - benzoxy ） - pheyl - acrylic ester and styrene. The structure and thermal properties of synthetic polymer were detected by wide angle X- ray diffraction（ WAXD）, thermogravimetry （TG） and differential seaning calorimetry （DSC） . The liquid crystal polymer was stationary liquid and was prepared the gas chromatography colunm, the column was used to determine several compounds and received good results. The liquid crystal polymer stationary liquid can be used at the temperature between 100℃ and 220℃.
