(Co) polymerization process of fluoro-containing monomers for obtaining hydrogen containing polymers
First Claim
1. A process for polymerizing unsaturated perfluoromonomers and fluoro-containing monomers, optionally in the presence of hydrogen-containing olefins for obtaining polymers containing hydrogen and fluorine, said process utilizing a previously prepared microemulsion consisting of the following components:
- (a) water;
(b) a fluoropolyoxyalkylene having hydrogen-containing end groups and/or hydroqen-containing repeating units;
(c) a fluorine-free organic radicalic initiator for the polymerization of fluoro-containinq monomers, soluble in component (b), said component c) is optionally dissolved in an hydrocarbon C1 -C20, of aliphatic, cycloaliphatic, aromatic or mixtures thereof, creating a mixture, optionally the hydrocarbon can contain halogen atoms, said mixture is soluble in component b); and
(d) a fluoro-containing surfactant.
