Abstract

A process for the manufacture of poly (ethylene terephthalate) by transesterification of dimethyl terephthalate with ethylene glycol and subsequent polycondensation, in the presence of catalysts, characterized in that cobalt tungstate is used as a polycondensation catalyst in amounts of 0.0005 to 0, 1% by weight in relation to the dimethyl terephthalate used.
