摘要:
A method for producing a liquid crystal polyester according to the present invention is a method for producing a liquid crystal polyester, comprising subjecting a composition in which a dicarboxylic acid compound, a hydroxycarboxylic acid compound, and a dihydroxy compound are contained to melt polycondensation, and subjecting an obtained reaction product to solid phase polycondensation, wherein the composition contains, based on a total of the dicarboxylic acid compound, the hydroxycarboxylic acid compound, and the dihydroxy compound, 2 to 30 mole % of a dicarboxylic acid compound represented by the following formula (1), and 40 to 80 mole % of p-hydroxybenzoic acid, a polycondensation temperature of the above melt polycondensation is 315° C. or less, and a polycondensation temperature of the above solid phase polycondensation is 315° C. or less.
