Radical copolymerization of vinylidene fluoride (1,1-difluoroethylene), hexafluoropropylene (hexa-fluoropropene-1), and perfluoroallyl fluorosulfate (fluorocopolymer C26-FS) was performed in a solution of 1,1,2-trifluoro-2,2,1-trichloroethane in order to create new low-molecular functional fluorocopolymers for cold vulcanization. The optimal copolymerization conditions were determined and a relationship was revealed between the microstructure of the C26-FS fluorocopolymer and its physicomechanical characteristics. 19F NMR spectroscopy was used to identify the structure and determine the number-average molecular mass and composition of the synthesized fluorocopolymers with a fluorosulfate group. The thermal stability in an inert medium and the glass transition temperature of S26-SF and the physicomechanical properties of their vulcanizates were studied. It was shown the properties and vulcanization duration of low-molecular functional fluorocopolymers is affected by the content of perfluoroallyl sulfate units (f = 2–4) relative to the vinylidene fluoride and hexafluoropropylene units in the polymer chain.
