Abstract:
A series of new main-chain liquid-crystal polymers (LCPs) were prepared from sebacoyl chloride ( SD ) and various amount of 4, 4-Dihydroxy-2, 2-dimethyl Benzalazine ( DDBA ) and isosorbide ( ISO ). The liquid crystal (LC) properties were investigated by polarized optical microscope (POM), differential scanning calorimetry (DSC) and X-ray diffraction measurements. P 1 exhibited a typical nematic thread texture, which contains no ISO . P 2 -P 7 are Sc* and N LCPs, which exhibited broken fan-shaped texture and droplet texture. The introduction of chiral units into the polymers led to a change of mesomorphase, as compared with P 1 .
