    摘要： The invention relates to a method of preparing wholly aromatic polyester including: mixing monomers, introducing the mixed monomers into a reactor having a rectangular or trapezoidal plate type stirring impeller, and polymerizing the introduced monomers through esterification with a power per unit volume of 10˜60 kW/m3, a length (L) to diameter (D) ratio of the stirring impeller is 1˜3:1, and a distance between the bottom of the reactor and a lower portion of the stirring impeller is 1/100˜ 1/15 times of the diameter (D); b) pulverizing the obtained polymer; and c) solid state polymerizing the pulverized polymer. The present invention also relates to a method of preparing wholly aromatic polyester having excellent heat resistant properties in which byproduct is effectively discharged by controlling a heating rate and reaction holding time between the weight loss initiating temperature and the melting point of a low molecular weight polymer generated in a melt polymerization in a solid state polymerization, adhesion does not occur, and discoloration due to heating does not occur.

    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.
