Title (EN) (PER)FLUOROPOLYETHER BLOCK COPOLYMERS
(FR) COPOLYMÈRES SÉQUENCÉS DE (PER)FLUOROPOLYÉTHER
Abstract:
(EN) The invention relates to (per)fluoropolyether block copolymers comprising: A) a fluoropolyoxyalkylene segment (chain Ra) comprising one or more units of formula (CHXCF2CF2O)- in which X is hydrogen or fluorine; B) a (per)fluoropolyoxyalkylene segment (chain Rf), that is to say a segment comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, said (per)fluoropolyoxyalkylene segment being different from chain Ra and having a molecular weight higher than 400 g/mol. These copolymers are endowed with improves lubricant properties or with improved water and oil-repellence properties.
(FR) Cette invention concerne des copolymères séquencés de (per)fluoropolyéther comprenant : A) un segment fluoropolyoxyalkylène (chaîne Ra) comprenant un ou plusieurs motifs de formule (CHXCF2CF2O)- où X est hydrogène ou fluor ; B) un segment (per)fluoropolyoxyalkylène (chaîne Rf), c'est-à-dire un segment comprenant des motifs récurrents comportant au moins une liaison éther caténaire et au moins un fragment fluorocarbone, ledit segment (per)fluoropolyoxyalkylène étant différent de la chaîne Ra et ayant un poids moléculaire supérieur à 400 g/mol. Ces copolymères sont dotés de propriétés lubrifiantes améliorées ou de propriétés hydrofuges et oléofuges améliorées.
