A series of semi-aromatic poly(imide-ester)s were prepared by the direct polycondensation of N -(4-carboxyphenyl) trimellitimide or N-(3-carboxyphenyl) trimellitimide with various pyromellitic diimide diols containing methylene spacer = 2-6, respectively. The effect of the amount of LiCl, pyridine,
## Abstract The liquid crystallinity of poly(ester‐imide)s obtained from biphenyl‐4,4′‐diol, ω‐amino acids and trimellitic anhydride is discussed. Four models 1–4, similar to repeating units I–III, were prepared from biphenyl‐4,4′‐diol or biphenyl‐4‐ol and 6‐phthalimido‐hexanoic acid, 6‐(4‐carboxyp
## Abstract The thermotropic phase behavior of a liquid‐crystalline poly(ether ester) derived from 4′‐hydroxybiphenyl‐4‐carboxylic acid and two different spacer diols (2‐methyl‐1,3‐propanediol and __R__‐1,3‐butanediol) has been analyzed by differential scanning calorimetry, real time synchrotron X‐
