Abstract

PURPOSE: To make it allowable to use curde terephthalic acid by conducting polycondensation reaction in the presence of specific polycondensation catalysts together with an addition of a specific amount of phosphorus compounds after an esterification index reaches at higer than 70%, in a process for preparing polyester from terephthalic acid.
