    摘要: There are provided novel vulcanizable compositions based on optionally fully or partly hydrogenated nitrile rubbers containing epoxy groups, and specific crosslinkers, which no longer require use of conventional crosslinkers, more particularly sulphur. The vulcanizates producible therefrom possess very good compression sets at room temperature, 100° C. and 150° C., and additionally exhibit high tensile stress combined with good elongation at break.
