Process for preparing perfluoropolyethers |
| abstract |
Process for preparing peroxidic perfluoropolyethers by oxidation of tetrafluoroethylene with oxygen, in liquid phase comprising a solvent and in the presence of a chemical initiator, 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. The process allows to increase the molecular weight of the perfluoropolyethers at the same content of peroxidic oxygen. |
