A series of polyesters derived from adipoyl chloride and alpha-(bis(2-hydroxy ethyl)amino)-omega-(4'-methoxybiphenyl-4-oxy)alkanes with different spacer lengths (Cn-diol, n=6,8,10) have been synthesized and characterized by NMR spectroscopy, SEC, DSC, and X-ray spectroscopy. All polyesters have a narrow distribution of molar masses (1.3-1.5), melting temperature of 55-62degreesC, and they melt in a narrow temperature range of 7-11degreesC. Although no liquid crystalline phase transitions were found, an ordered structure was observed by XRD experiments and was ascribed to a crystal smectic phase.
