    摘要: Provided is a method of preparing a wholly aromatic liquid crystalline polyester resin and a wholly aromatic liquid crystalline polyester resin prepared by the method, and a compound of the wholly aromatic liquid crystalline polyester resin. The disclosed method of preparing the wholly aromatic liquid crystalline polyester resin includes a step (a first temperature increasing step) of increasing the temperature of a reaction mixture including at least one monomer at a first temperature increasing rate up to a first temperature; a step (an isothermal maintaining step) of maintaining the reaction mixture that passed through the first temperature increasing step at the first temperature for a first time; and a step (a second temperature increasing step) of increasing the temperature of the reaction mixture that passed through the isothermal maintaining step at a second temperature increasing rate.
