    摘要: The present invention provides a method for manufacturing a wholly aromatic liquid-crystalline polyester resin comprising the steps of: 1) acylating the hydroxy group of major monomer components selected from the group consisting of aromatic hydroxycarboxylic acid, aromatic diol and aromatic dicarboxylic acid, with an acylating agent, provided that said major monomer components comprise at least one of aromatic hydroxycarboxylic acid and aromatic diol; and 2) polycondensing said major monomer components of which hydroxy group is acylated, wherein, the polycondensation reaction is carried out in the presence of a metal dihydrogen phosphate in an amount of 1-5000 ppm based on the total monomer components, and a liquid-crystalline polyester resin manufactured by the method and a composition comprising said resin.
