Abstract: The present invention relates to non-aqueous fluoropolymer compositions useful for the preparation of polymeric materials.

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.

Abstract: A polymer [polymer (P)] comprising a plurality of (per)fluoropolyether (PFPE) segments [segments (SRF)] joined together by hydrogenated (poly)ether segments [segments (SH)], said polymers (P) having two end groups [groups (E)], each group (E) comprising a hydroxy or a leaving group, with the proviso that the hydrogenated (poly)ether segment (SH) is not a segment of formula —CH2OCH2 OCH2— is herein disclosed. Disclosed is also a method for the manufacture of polymer (P) and a polymer obtainable by full or partial fluorination of polymer (P). Polymer (P) and polymers obtainable therefrom by full or partial fluorination can be conveniently used in the manufacture of lubricant compositions or of compositions for imparting hydro-/oleo-repellence to substrates. Said polymers can also be used as intermediates for the manufacture of other polymers or block copolymers.
