Abstract

A process for the preparation of polyethylene terephthalate wherein dimethyl terephthalate and ethylene glycol are transesterified and the resulting transesterified product is polycondensed in the presence of a polycondensation catalyst, characterized in that the transesterification reaction is carried out in the presence of a cerium or lead acetyl acetonate catalyst.
