Abstract: A method for the manufacture of fluorinated polymers and polymers obtainable therefrom are herein disclosed. The method envisages the reaction of a) first reagent [reagent (R1)] which is an alcohol selected from a (per)fluoropolyether (PFPE) alcohol a fluoroalkylene diol and a mixture thereof; b) a second reagent [reagent (R2)] which is a sulfonic ester of a PFPE, a sulfonic diester of a fluoroalkylene diol or a mixture thereof and, optionally, c) a third reagent which is a mono-functional (per)haloalkyl alcohol or a sulfonic ester thereof in the presence of an organic or inorganic base. At least reagent (R1) is a PFPE alcohol (A) or at least reagent (R2) is a PFPE sulfonic ester (B) and the overall equivalents of alcohols are the same as the overall equivalents of sulfonic esters. The method allows to obtain in a convenient way non-functional polymers comprising at least a PFPE segment and having high molecular weight.
