摘要
本文从理论上讨论了半刚性液晶共聚酯及其柔性同系物PET的热力学相容性,并用热台偏光显微镜、DSC、光学解偏振仪、X光衍射等实验手段对其相容性进行了研究,最后得出了该共混体系是一个部分互溶的相分离体系的结果.
In this paper the thermodynamic compatibility of semi-rigid liquid crystal copolymer and its flexible homolog PET were discussed in theory. By means of polarized microscope, DSC, SEM, DLI, X-ray difraction metheds, etc. the compatibility of the polymer blend was studied. At last the result that polyblend was a partially miscible phase-seperated system was obtained.
