Summary:Perfluoropolyethers having structural formula R1O-(CF2O)n-(CF2CF2O)mR2 (I) wherein: R1 is -CH3 or -C2H5; R2 is equal to R1 or -CF2H n is 0 or an integer from 1 to 100; m is an integer from 1 to 100 or, when R2 is -CF2H, m can also be 0; the oxyfluoroalkylene units -(CF2CF2O)- and -(CF2O)- are statistically distributed along the polymer chain.
