Abstract: The liquid crystalline properties of novel main chain polyazomethineethers series(SBn, n=3-8.10) were characterized by polarized microscopy with a hot stage, DSCand X-ray diffractions.The disclination and band texture were observed for seven polymers.Their melting points are affected by number of methylene group in the flexible units and show an odd-even effect in zigzag manner.

Key words: Polyazomethineethers, Liquid crystal, Nematic phase, Band texture
