Abstract
New liquid-crystalline polyesters were synthesized with the main chain cont aining mesogenic fragments obtained from terephthaloyl-bis(hydroxybenzoyl c hloride) and 1,6-hexanediol and tautomeric fragments formed from terephthal oyl-bis(hydroxybenzoyl chloride) and bis(6-hydroxyhexyl)-1,4-cyclohexanedio ne-2,5-dicarboxylate. Their enolization was studied by H-1 NMR spectroscopy , and a linear relationship was established between the enolization ratio a nd the proportion of the mesogenic fragment.
