| Abstract: | A series of wholly aromatic copolyesters were prepared from p acetoxybenzoic acid,hydroquinone diacetate and isophthalic acid. The molecular structure and mesomorphic behavior of the copolyesters were characterized with IR,DSC and hot stage polarizing microscopy. The results show that copolyestsrs have low melting temperature and stable mesophase in a broad temperature range in some composition range. |
