Abstract

PURPOSE:To provide the title polyester having a high strength, a high elasticity, lowly anisotropic mechanical characteristics in molding and a melt-moldability, by incorporating thereinto four kinds of specific constituent units. CONSTITUTION:20-80mol.% arom. hydroxycarboxylic acid (deriv.) (e.g., P- hydroxybenzoic acid) and 5-50mol.% arom. dicarboxylic acid (deriv.) (e.g., terephthalic acid) are reacted with 5-50mol.% arom. diol (deriv.) (e.g., hydroquinone) and 0.1-40mol.% 2-methyl-1,4-butanediol to prepare a cholesteric liquid crystal polyester having constituent units of formulae I-IV [wherein Ar<1>-3 are each a 6-20C bivalent arom. hydrocarbon group(s) or the like having an arom. ring, provided that 1,4-phenylene, 2,6-naphthyl and 4,4'-biphenyl accounts for at least 60mol.% of Ar<1>].
