Patent ID: 10179836

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.
