【摘要】 以２，４－二异氰酸甲苯酯（２，４—ＴＤＩ）、胆甾醇、丙烯酸β－羟丙酯为原料，合成了含胆甾醇介品基团的侧链液晶高分子、并用ＮＭＲ、ＩＲ和元素分析方法对其结构进行了鉴定。聚合物的相转变温度和形态织构用ＤＳＣ、Ｘ－射线衍射和偏光显微镜进行了测定和观察。更多还原

【Abstract】 In this paper, a new side-chain liquid crystalline Polymer (Poly A) with cholesteryl as mesogenicgroups was synthesized from 2,4-TDI, cholesterol and β-hydroxypropyl acrylate using CHl13 as a solvent. Monomer A was characterized by IR, NMR and Elemental Analysis. The phase transition temperature and liquid crystalline phase texture of polyA were investigated by DSC, X-ray diffraction andpolarized microscopy.更多还原
