Abstract
A sort of process for preparing peroxidic perfluoropolyethers, having a molecular M of over 5000 and the PO value under 4% of the total weight, being formed the process by the following: reaction of tetrafluoroethylene with oxygen in a liquid phase containing a solvent while the temperature is maintained at between -100 DEG C and -20 DEG C, with chemical initiator, formed by perfluoropolyethers having as many as 3 carbon atoms, at a pressure between 2 and 15 absolute atm and operating with a molar ratio of the tetrafluoroethylene to the chemical initiator higher than 35.
