MICROEMULSIONS OF FLUOROPOLYOXYALKYLENES IN ADMIXTURE WITH HYDROCARBONS, AND THEIR USE IN (CO) POLYMERIZATION PROCESSES OF FLUORINATED MONOMERS

摘要

Microemulsions are described which comprise: (a) water; (b) a fluoropolyoxyalkylene having hydrogenated end groups and/or hydrogenated repetitive units; (c) an hydrocarbon C1-C20, preferably C1-C12, of aliphatic, aromatic, or mixed type, optionally containing halogens, preferably chlorine and/or bromine; (d) a fluorinated surfactant. Such microemulsions can be used in radical (co)polymer-ization processes in aqueous emulsion of one or more fluorinated olefinic monomers, optionally in association with one or more non fluorinated olefins.
