应用Ｘ射线衍射、偏光显微镜及电子显微镜研究了胆甾液晶与甲基丙烯酸甲酯（ＭＭＡ）─甲基丙烯酸丁酯（ＢＭＡ）无规共聚物共混体系的形态结构。研究了体系的结晶态及液晶态的行为和共聚物含量及组成对光学织构的影响。
The morphological structure of the blend of cholesteric liquid crystal and methyl methacrylate (MMA) -methacrylate (BMA) random copolymer was studied by X-ray diffraction, polarized light microscope and electron microscope. The crystalline and liquid crystalline behavior of the system and the effects of the copolymer content and composition on the optical texture were investigated.
