Summary: | Described are new perfluoropolyethers of general formula: wherein: A and B are end groups, X represents a group (R'O)mR'' wherein R' is selected from -CF2-, -CF2-CF2- and R'' is a perfluoroalkyl group; and m ranges from 0 to 6. The invention also relates to processes for preparing said perfluoropolyethers and other classes of non-peroxidic perfluoropolyethers derived therefrom. |
