摘要

<正> Several novel aromatic liquid crystalline copolyesters with regular sequence structure were prepared by melt Sehotten-Baumann polycondensation via complex monomer. Polarizing microscope with hot stage

thermal analysis and X-ray diffraction were used to investigate the structure and properties of the copolyesters. The effects of structural units

such as flexible spacer

noncolinear meta-linked phenylene unit

crankshaft unit

kink with flexible bridging unit and various substituted benzene rings on melting temperature of aromatic copolyesters were studied and discussed on the basis of crystalline structure of the polymers.
