Improvements in the production processes of highly polymerized polyethylene terephthalates, characterized in that they comprise the use, as a polycondensation catalyst, of at least one antimony compound in which the element Sb is present as an antimony radical in combination with an aromatic organic radical, which it can be a phenyl or naphthyl radical, simple or substituted, in which the oxygen atom is directly linked to a carbon atom of the aromatic nucleus.
