Abstract
A dicarboxylic acid, N,N′-hexane-1,6-diylbis(trimellitimide), was prepared by the reaction of trimellitic anhydride with 1,6-hexane diamine. From the diacid, a series of copoly(ester imide)s had been synthesized by thermal condensation with p-hydroxybenzoic acid and diphenols with different structures. Properties of the resulting copoly(ester imide)s were characterized by polarized light microscopy, differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD). Most of the copoly(ester imide)s formed a nematic phase over a wide temperature range above their melt. The effects of the copoly(ester imide)s composition and the structures of diphenols on the temperature related to liquid crystalline transition were investigated.
