    摘要： 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.

    摘要： Disclosed are mixtures containing: mono- and bi-functional polymers [polymers (P-A) and (P-B)] comprising a plurality of (per)fluoropolyether segments [segments (SRF)] joined together by hydrogenated (poly)ether segments [segments (SH)], said polymers having two ends, wherein one or both ends comprises a hydroxy or a leaving group; a non-functional polymer comprising a plurality of (per)fluoropolyether segments (S) joined together by hydrogenated (poly)ether segments (SB), with the proviso that the hydrogenated (poly)ether segments (SRF) are not segments of formula —CH2OCH2OCH2—. Disclosed are also monofunctional polymers (P-A) that can be isolated from such mixtures. Methods for the obtainment of the mixtures and for separating the polymers therein contained are also provided, as well as methods of using the mixtures or each polymer therein contained as intermediates or building blocks for the synthesis of other polymers or as ingredients of compositions.
