VULCANIZABLE COMPOSITIONS BASED ON NITRILE RUBBERS CONTAINING EPOXY GROUPS

摘要

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.
