A New All-Aromatic Thermotropic Liquid Crystalline Polyester Derived from Acetylhydroquinone

Department of Chendstry, Jilin University, Changchun 130023

Received Date: 28 October 1996

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℃.Above Tg.the sample exhibited typical nematic texture.It showed high thermal stability (Td=487℃).
