Abstract

The possibility of using fluoroperoxides derived from polyfluorinated di- and tetracarbonyl compounds as vulcanizing agents for SKF-32 and SKF-260 fluororubbers was examined. The vulcanizates obtained are characterized by the tensile strength of up to 5.1 MPa and relative elongation at break of up to 130%. The resistance of the vulcanizates to H2SO4 and H2SO4–HNO3 mixture increases by a factor of approximately 1.5–2, and the resistance to toluene and acetic acid, by 20–30% relative to the vulcanizates obtained from the same rubbers using benzoyl peroxide or Peroxymon F40 as a vulcanizing agent.
