Abstract

PURPOSE: To make it allowable to use crude terephthalic acid by conducting polycondensation reaction in the presence of specific polycondensation catalysts after an addition of a specific amount of phosphorus compounds at the stage wherein an esterification index reaches at higher than 80%, in a process for preparing polyester from terephthalic acid.
