Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing a fluoropolymer in a liquid reaction medium, comprising the following steps:provide a reactor containing a liquid reaction medium comprising waterintroduce in said reactor ethylene monomers and fluorinated monomers, said fluorinated monomers being selected from tetrafluoroethylene (TFE), chlorotrifluoroethylene (CTFE) or mixtures thereof,pressurize the reactor,initiate polymerization feeding into said reactor a redox initiator comprising an oxidising agent and a reducing agent, wherein said reducing agent in said redox couple initiator is free from sulphur atoms having an oxidation number of 4 or below, wherein the reaction medium is free of fluorinated surfactants.
