| Abstract: | his paper deals with synthesis of mesogenic condensation monomer, bis- (3- methoxy - 4 -- hydroxybenzylidene ) -- 4, 4' -- diimidobiphenyl (biphenol ), seven main chain thermotropic polyazomethine-- ethers made from biphenol and a, ω -dibromoalkane by phase -- transfer--catalysis polyetherification reaction are discussed.Ther structure have ho characterics by 1H--NMR, IR spectra and element analysis. The effect of alkali aqueous concentration on solubility has been investigated. The banded texture of oriented specimens remains almost unchanged during the melting transition but birefringent weakens and the banded texture graduallydisappears with increasing temperature. |
