Abstract
Microemulsions are described which comprise: PA1 (a) water; PA1 (b) a fluoropolyoxyalkylene having hydrogenated end groups and/or hydrogenated repetitive units; PA1 (c) an hydrocarbon C.sub.1 -C.sub.20, preferably C.sub.1 -C.sub.12, of aliphatic, aromatic, or mixed type, optionally containing halogens, preferably chlorine and/or bromine; PA1 (d) a fluorinated surfactant. Such microemulsions can be used in radical (co)polymerization processes in aqueous emulsion of one or more fluorinated olefinic monomers, optionally in association with one or more non fluorinated olefins.
