ABSTRACT:
Perfluoropolyethers having fluorinated epoxy groups positioned along their perfluoropolyether chain, and free from peroxidic oxygen, are obtained using a low-temperture 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 conjugated diene, and of the subsequent photochemical decomposition of the peroxy groups contained in the photoxidation product, carried out by treating the peroxy-groups-containing product with U.V. light at a temperature within the range of from 0.degree. C. to 160.degree. C. Derivatives of said epoxy containing perfluoropolyethers in which the epoxy groups have been turned into functional groups.
