Abstract
The invention discloses a process for the preparation of fluorinated polymers by miniemulsion polymerization of a mixture of fluorinated and nonfluorinated monomers in the absence of organic solvent. This polymerization process makes it possible to obtain an aqueous emulsion of fluorinated polymers devoid of coagulum.
