应用ＤＳＣ、偏光显微镜和动态力学分析，研究了胆甾液晶与甲基丙烯酸甲酯－甲基丙烯酸丁酯无规共聚物共混体系的相容性及相态转变．表明共聚物的组成、分子量大小可抑制胆甾液晶的相态转变．给出了形成稳定相容的液晶／高分子体系的最佳条件．
The compatibility and phase transition of cholesteric liquid crystal with methyl methacrylate-butyl methacrylate random copolymer blends were studied by DSC, polarized light microscopy and dynamic mechanical analysis. It shows that the copolymer composition, molecular weight can inhibit the cholesteric liquid crystal phase transition. The optimal conditions for forming a stable and compatible liquid crystal / polymer system are given.
