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 groupsand/or hydrogenated repetitive units;(c) an hydrocarbon C1-C20, preferably C1-C12, of aliphatic,aromatic, or mixed type, optionally containinghalogens, 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 morefluorinated olefinic monomers, optionally in associationwith one or more non fluorinated olefins.
