| Abstract: | A series of polyester based liquid crystalline ionomers(LCI) with various sulfonate group content were prepared from p acetoxybenzoic acid and sulfonated PET ionomers through melt copolycondensation. The dissoluble and indissoluble parts were seperated, and the reason of this phenomenon was discussed. The structure of the LCIs and the concentration of the ionic groups were characterized by FT IR analysis and atomic absorption spectrometry respectively. The thermal properties of the synthesized polymers were investigated by DSC and TGA. The polarizing light microscopy experimental results of the quenched samples show that the prepared polymers belong to a kind of nematic thermotropic liquid crystals. |
