METHOD FOR PREPARING AN AROMATIC LIQUID CRYSTAL POLYESTER RESIN AND METHOD FOR PREPARING A COMPOUND OF AROMATIC LIQUID CRYSTAL POLYESTER RESIN

摘要

Disclosed are a method for preparing an aromatic liquid crystal polyester resin and a method for preparing a compound of aromatic liquid crystal polyester resin. The method for preparing an aromatic liquid crystal polyester resin comprises the steps of: acetalizing a first monomer having an amino group through the reaction between the first monomer and carboxylic acid anhydride; acetalizing a second monomer having a hydroxyl group and not including an amino group through the reaction between the second monomer and additional carboxylic acid anhydride; and synthesizing an aromatic liquid crystal polyester prepolymer through the polycondensation reaction among the acetalized first and second monomers and dicarboxylic acid. Further, the prepared aromatic liquid crystal polyester resin is used for preparing the compound of same.
