摘要
合成了对羟基苯甲酸二聚体 (DHBA)、四聚体 (THBA) ,并将其接枝到苯乙烯马来酸酐共聚物(SMA)上得到侧链液晶高分子 .FT IR、DSC、偏光显微镜等分析结果表明由于液晶基元的引入提高了聚合物的耐热性 .
Dimer and tetramer of phydroxy benzoic acid(HBA) were synthesized and grafted to styrenemaleic anhydride copolymer(SMA) to produce side chain liquid crystalline polymers(LCP). FTIR,DSC and POM were used to characterize the structure of LCP. It has been found that the temperatures of glass transition of LCP rised because of the induction of liquid crystalline unit on SMA main chain.
