Two different series of new aromatic liquid crystalline (LC) polyesters were prepared from 3‐phenyl‐4, 4'‐biphenyldicarboxylic acid (PBDA) and 1‐phenyl‐2, 6‐naphthalenedicarboxylic acid (PNDA). PBDA and PNDA were polymerized with various aromatic diols such as hydroquinone, substituted hydroquinones, isomeric naphthalenediols and 4, 4'‐biphenol, and the resulting polyesters were characterized by DSC, WAXD, and on a cross‐polarizing microscope for the study of their thermal transition and crystallization properties, and mesophases formed therefrom.
