Synthesis and characterization of hyperbranched liquid crystalline polymer
Hyperbranched liquid crystalline polymer (HLCP) were prepared by pentaerythritol with 1,2,4-benzenetricarboxylic anhydride(BTCA) and phydroxy benzoic acid. The thermotropic properties, the melting point (Tm) and the isotropization temperature (Ti) of the synthesized HLCP were characterized by differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR) and polarizing optical microscopy (POM). It showed that the new reactive thermotropic liquid polymer containing polyester mesogenic units exhibited thermotropic liquid crystalline properties between 140℃ and 230℃.
