| description | The invention discloses a poly-p-phenylene terephthamide liquid crystal polymer and a preparation method thereof. According to the invention, a series of novel poly-p-phenylene terephthamide are obtained through copolymerization of functionalized aromatic diether diamine, paraphthaloyl chloride and p-phenylenediamine, the intrinsic viscosity of the prepared polymer is 1.37-2.44 dL/g, and the polymer can be completely dissolved in NMP under a heating condition; in a N2 atmosphere, the 5% thermal decomposition temperature of the polymer is 472 DEG C or above, and the glass-transition temperatureis 235-292 DEG C, so that the heat resistance of polyarylamide is maintained, and the processing formability of PPTA is improved; the prepared polymer has excellent heat resistance and mechanical properties, is good in solubility, can form a high-transparency nematic main chain type thermotropic liquid crystal polymer, and is easy to process and mold; and due to conjugation of aromatic groups, the dielectric constant of |
