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 wolframate phosphoric acid in amounts of 0.0005 to 0.1 is used as the polycondensation catalyst. % by weight, based on the dimethyl terephthalate used.
