The wholly aromatic four-component copolyesters were prepared from p-acetoxy-benzoic acid
hydroquinone diacetate
2
6-naphthalene dicarboxylic acid and isophthalic acid by melting polycondensation. The melted copolyesters exhibit good liquid crystal-linity in some range of the copolyester compositions.The relationship of composition and properties
DSC thermogram characters and mesomorphic behavior were discussed.
