Abstract: The invention relates to the use of polymer particles in the form of filaments formed by block copolymers, as viscosifiers or agents that modify the rheology of organic or aqueous solutions. More specifically, the invention relates to the use of said crosslinked filamentous polymer particles for improving the resistance to heat ageing of an organic or aqueous solution.

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.
