Abstract

Process for the continuous production of polyesters of terephthalic acid and/or isophthalic acid, starting from melting masses of bis-2-oxyethylterephthalate and/or of bis-2-oxyethylisophthalate, in the presence of a polycondensation catalyst, undergoing polycondensation the accumulated melt with heat supply and in vacuum, characterized by causing pressures that vary suddenly and locally within the accumulated melt.
