摘要：

Six dicarboxylic acids were prepared from benzophenone-3,3',4,4'-tetracarboxylic dianhydride (BTA) and 4-aminobutyric acid, 5-aminovaleric acid, 6-aminocaproic acid, 7-aminoheptanoic acid lactam, 11-aminoundecanoic acid, and 12-aminododecanoic acid. These diacids were condensed with the diacetates of hydroquinone, 2,6-dihydroxynaphthalene or 4,4'-dihydroxybiphenyl. The resulting poly(ester imides) were characterized by inherent viscosity elemental analyses, differential scanning calorimetry (DSC), observation under polarized light, and WAXS measurements. Formation of a smectic melt was found for almost all polymers containing 4. 4'-dihydroxybiphenyl. These thermotropic poly(ester imides) were also characterized by thermomechanical and thermogravimetric analyses, and an odd-even effect was found for the heat-distortion temperatures.
