Abstract
A process for the continuous polycondensation of precondensates coming from a continuous transesterification of for example dimethyl terephthalate with ethylene glycol or a continuous esterification of for example terephthalic acid with ethylene glycol, optionally with the addition of catalysts, characterized in that the volatile compounds released in the reaction in at least one open channel indirectly heated with a heating medium are separated from the reaction zone.
