Abstract
THE PRESENT INVENTION RELATES TO A METHOD FOR PRODUCING A POLYESTER INCLUDING SUBJECTING A DIOL COMPONENT AND A DICARBOXYLIC ACID TO AT LEAST ONE REACTION OF AN ESTERIFICATION REACTION AND AN ESTER EXCHANGE REACTION AND FURTHER A POLYCONDENSATION REACTION, WHEREIN THE POLYCONDENSATION REACTION IS CARRIED OUT UNDER REDUCED PRESSURE, 1,4-BG HAVING GONE THROUGH A VACUUM APPLYING APPARATUS PROVIDED WITH A VAPOR EJECTOR (A1, A3, B1, B3, B5, C1, C3, C5) IS A MAIN COMPONENT OF THE DIOL COMPONENT, AND A PH OF THE 1,4-BG SUPPLIED INTO A VAPOR GENERATION APPARATUS (K) FOR VAPOR EJECTOR DRIVING IS 7.0 OR MORE AND NOT MORE THAN 11.5. (FIG. 3)
