Abstract
Fluorinated olefinic monomers, optionally in association with non-fluorinated olefins, are (co)polymerized in aqueous emulsion in the presence of a hydrophilic solvent and of a fluoropolyoxyalkylene having hydrogenated end groups and/or hydrogenated repetitive units. In this way it is possible to obtain high productivities, close to those obtainable using a hydrophilic solvent and a chlorofluorocarbon.
