Abstract
A process for polymerizing or copolymerizing fluorinated monomers, in an aqueous dispersion, by the use of radicalic starters and of fluorinated surfactants, characterized in that it is operated in the presence of perfluoropolyether having neutral end groups, being liquid under the polymerization conditions and in the form of an aqueous emulsions, in order to increase the polymerization rate.
