Thermotropic Liquid Crystalline Polyarylates

  • Toshihide Inoue

Abstract

Recently thermotropic liquid crystalline polyarylates (TLCPs) have been attracting much attention because of their very high modulus, excellent processability, thermal resistance, dimentional stability, flame resistance and chemical resistance, and the possibility of being a substitute for Al. However, TLCPs have also some serious problems such as mechanical anisotropy, low weldline strength and fibrization (delamination), and the modulus is still lower than that of Al. We have been working on the preparation of novel TLCPs with higher weldline strength and resistance to fibrization and found that TLCPs derived from 4,4′-diphenyldicarboxylic acid(BB) would be promising materials as a substitute for Al.
