    摘要： A wholly aromatic copolyester, comprising; the structural units I, II, and III represented by the following formulas,

    wherein
    in the structural unit I, the two carbonyl groups are present on the benzene ring at the meta- or para-position to each other and
    in the structural unit II, Ar is an aryl group, each of X and Y independently is hydrogen or an alkyl group of 1 to 3 carbon atoms, and Z is hydrogen or a halogen,
    the molar ratio of the structural unit III to the structural unit II (III:II) being from 26:74 to 60:40.
    The wholly aromatic copolyester exhibits well-balanced characteristics in moldability, heat resistance, solvent resistance, and heat stability, and is useful especially as the material for electric or electronic parts and car parts.
