摘      要：Four novel copoly（ester-imide）s based on 3,3′,4,4′-biphenyltetracarboxylic dianhydride, bis（trimellitic acid anhydride） phenyl ester and di-p-aminophenyl ester of dicarboxylic acids were synthesized via two-step method in order to investigate whether two imide mesogenic units with different conformation and polarity could control the formation of LC-phase. Polarizes light microscopy （PLM） and differential scanning calorimetry （DSC） have shown that three polymers formed the nematic phase with ＂thread schlieren texture＂ and a polymer formed the nematic phase with ＂Inversion walls texture＂.
