Реферат: Fluorinated organic sulfone compounds are used as reaction media in the production of low-viscosity fluoro- rubbers by radical-initiated polymerization of fluoro monomers. A process for the production of low-viscosity fluoro-rubbers, comprises radical-initiated polymerization of fluoro monomers in presence of compound(s) of formula: R<1>-SO2-R<2>(I); or (II) and optionally a molecular weight regulator; R<1> = F or 1-4C perfluoroalkyl; R<2> = 1-4C perfluoroalkyl; n = 4 or 5.
