Abstract: Anew kind of epoxy resins with ester mesogen was synthesized and characterized by means of IR, 1H MMR, DSCand POM. It was testified to be an epoxy-terminated oligomer containing di(p-hydroxyl benzoic acid) hydroquinone ester as mesogenic unit. The numger average molecular weight was measured by end-group analysis and the effect of reaction ratio on the molecular weight equivalent and the liquid crystalline properties of the products was also discussed.

Key words: Liquid crystalline epoxy resin, Ester mesogen unit, Oligomer
