| abstract |
The invention relates to novel vulcanizable compositions that are based on optionally fully or partially hydrogenated nitrile rubbers, which contain epoxy groups, and special cross-linking agents, which no longer require the use of conventional cross-linking agents, such as sulfur in particular. The vulcanized rubbers that can be produced therefrom have very good compression set at room temperature, 100°C and 150°C, and also exhibit high tensile stress together with good elongation at break. |
