    摘要: 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.

    摘要: In a process of (co)polymerization in aqueous emulsion of fluorinated olefinic monomers it is added to the reaction medium a microemulsion of fluoropolyoxyalkylenes having hydrogenated end groups and/or hydrogenated repetitive units. A remarkable reduction in the reaction induction period is so obtained, with formation of a product with improved mechanical properties and higher thermal and chemical resistance.
