Perfluoropolyethers free from peroxidic oxygen and containing perfluoroepoxy groups positioned along their perfluoropolyether chain, and their derivatives |
| abstract |
Perfluoropolyethers having fluorinated epoxy groups positioned along their perfluoropolyether chain, and free from peroxidic oxygen, are obtained by means of a low-temperature oxidation process, in the liquid phase, with molecular oxygen and in the presence of U.V. light, of a mixture of a perfluorinated monoolefin and a perfluorinated configurated diene, and of the subsequent photochemical decomposition of the peroxy groups contained in the photooxidation product, carried out by treating the peroxy-groups-containing product with U.V. light at a temperature comprised within the range of from 0°C to 160°C. Derivatives of said epoxy containing perfluoropolyethers in which the epoxy groups have been turned into functional groups. |
