Abstract

A process for the production of polymers, which consists in reacting ethylene glycol and terephthalic acid in molar proportions comprised between 1.0 and less than 2 moles of ethylene glycol per mole of terephthalic acid in the presence of a pre-formed amount of such polymers, at a temperature between 200º and 300ºC and at a pressure lower than the vapor pressure of ethylene glycol at the reaction temperature.
