Abstract
Polymerization process of unsaturated pefluoromonomers, fluoro-containing monomers and optionally in the presence of hydrogen containing olefins, for obtaining polymers contaning hydrogen and fluorine, which utilizes a microemulsion comprising the following components: PA1 (a) water; PA1 (b) a fluoropolyoxyalkylene having hydrogen-containing end groups and/or hydrogen-containing repeating units; PA1 (c) a fluorine-free organic radicalic initiator for the polymerization of fluoro-containing monomers, soluble in component (B); PA1 (d) a fluoro-containing surfactant.
