Abstract

A process for the preparation of polyethylene terephthalate by esterification of terephthalic acid with glycol followed by polycondensation of the ester mixture formed, characterized in that the esterification reaction takes place in a medium of glycol esters of terephthalic acid in which the polar ratio of terephthalic acid combined with glycol, both free and combined, is, at least, 0.55.
