Abstract:
An improved polymerization and process method allows the production of special nitrile rubbers which are characterized by a specific anion content and an excellent storage stability and allow a particularly good vulcanization rate and moreover result in vulcanized materials that have advantageous properties, especially with regard to the contact with metal components of molded parts based on said vulcanized materials.
