| titleOfInvention | Method for producing aromatic polyester |
| abstract | A polycondensation reaction can be carried out in a short time even when a monomer having low reactivity is used, and no solidification of the polymer occurs at the stage of the polycondensation reaction, and the residual amount of the monomer is reduced. To provide a method for producing an aromatic polyester. A phenolic hydroxyl group of an aromatic diol and an aromatic hydroxycarboxylic acid is subjected to an acylation reaction with a fatty acid anhydride to obtain an acylated product, and then a polycondensation reaction between the acylated product and an aromatic dicarboxylic acid is performed. A method for producing an aromatic polyester, wherein the condensation polymerization reaction is carried out in the presence of a phosphoramide represented by the following formula (1). (In the formula, E represents oxygen or sulfur, Y represents a hydrogen atom or the like, and Ra and Rb represent an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 12 carbon atoms.)
