摘要：
A method of preparing perfluoropolyethers having a regulated molecular weigh starting from the product obtained by photochemical oxidation of C 2 F 4 and having a various content of oxygen peroxide, consisting'in heat-treating the peroxidized product in order to partially remove the oxygen peroxide till reducing it to a relatively lowvalue which is prefixed as a function of the molecular weight to be obtained for the final product, and in the subsequent treatment with gaseous fluorine at high temperature.
