Zusammenfassung:	Novel vulcanisable compositions are provided, based on nitrile rubbers that are optionally fully or partially hydrogenated and contain epoxy groups, special acid crosslinkers and crosslinking accelerators, whereby the use of conventional crosslinking agents, in particular sulphur, is no longer required. The vulcanised materials thus produced have a very good compression set at room temperature, at 100°C and at 150°C and further show a high tensile strength, good elongation at rupture.
