文摘A new all aromatic thermotropic liquid crystalline polyester from acetylhydroquinone was prepared by nucleophilic substitution reaction and characterized for its thermotropic liquid crystalline property. The new polyester was amorphous which had glass transition at 274 degrees C. Above Tg, the sample exhibited typical nematic texture. It showed high thermal stability (Td=487 degrees C).
