Improvements introduced in the object of the main patent, that is, in a process for the polycondensation of esters of melic diglycol terephthalate, characterized in that during the melt condensation a stream of vapors heated to 250 to 320ºC is passed through the melt. Preferably up to 280º, of paraffinic hydrocarbons or aromatic or hydroaromatic combinations that do not contain any functional group. (Machine-translation by Google Translate, not legally binding)
