The perfluoropolyethers, prepared through this method, can be used as initiators of radical polymerisation and as cross-linking agents for polymers. The method is very flexible and allows to derive a wide range of products with various structural characteristics by changing the reaction conditions. It uses a chemical initiator instead of the delicate and complicated photochemical technology. According to the method, the peroxidic perfluoropolyethers contain perfluoroalkyleneoxy links with at least two carbon atoms and one or more perfluoroolefins (excluding tetrafluoroethylene, which is used separately) react with oxygen in liquid phase at a temperature not exceeding 50 degrees C and in the presence of one or more compounds, containing one or more F-X links, where X is chosen from the F, O and Cl containing group.
