METHOD OF PREPARING WHOLLY AROMATIC LIQUID CRYSTALLINE POLYESTER RESIN AND RESIN PREPARED BY THE METHOD, AND COMPOUND INCLUDING THE RESIN

摘要

PURPOSE: A manufacturing method of a wholly aromatic liquid crystal polyester resin, a resin manufactured by the same and a compound including the resin are provided to enhance heat resistance and polymerization properties. CONSTITUTION: A manufacturing method of a wholly aromatic liquid crystal polyester resin comprises the following steps: increasing the temperature of a reactive mixture including one or more kinds of monomers up to a first temperature at a first heating rate; maintaining the reactive mixture at the first temperature for a first time period; and increasing temperature of the reactive mixture at a second heating rate. The first heating rate is 0.5-1.5 deg. Celsius/min. The first temperature is 250-270 deg. Celsius. The first time period is 1-2 hours. The second heating rate is 0.5-1.5 deg. Celsius/min.
