Abstract

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.
