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.

Abstract: 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 (SRF) joined together by hydrogenated (poly)ether segments (SH), with the proviso that the hydrogenated (poly)ether segments (SH) 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.
