Title (EN) SYNTHESIS OF SURFACTANT-FREE POLY(VINYLIDENE FLUORIDE) LATEXES VIA RAFT EMULSION POLYMERIZATION
(FR) SYNTHÈSE DE LATEX DE POLY(FLUORURE DE VINYLIDÈNE) EXEMPTS DE TENSIOACTIF PAR POLYMÉRISATION RAFT EN ÉMULSION
Abstract:
(EN) The present invention relates to a process for producing a stable fluorinated latex by emulsion polymerization in the absence of fluorinated surfactant, stabilized by an amphiphilic block copolymer formed in situ. The invention also concerns the aqueous dispersion comprising the fluorinated polymer chains and the amphiphilic block copolymers, obtained by this process.
(FR) La présente invention concerne un procédé de production d'un latex fluoré stable par polymérisation en émulsion en l'absence de tensioactif fluoré, stabilisé par un copolymère séquencé amphiphile formé in situ. L'invention concerne également une dispersion aqueuse, comprenant les chaînes polymères fluorées et les copolymères séquencés amphiphiles, obtenue par ce procédé.
