FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry. Vulcanisable composition contains one epoxy group-containing hydrogenated nitrile rubber, which contains repeating units of one conjugated diene, one α,β-unsaturated nitrile and one or more additional copolymerisable of monomers; one Lewis base and/or Bronsted base as a cross-linking agent; one cross-linking accelerator. Lewis base and/or Bronsted base differ from compounds, which form a group of cross-linking accelerators.
EFFECT: invention makes it possible to limit use of peroxide or sulphur-containing cross-linking agents in vulcanisable compositions, optimise residual compression deformation at high temperatures during prolonged stress.
