Abstract

New halogenated butyl rubbers, which have a defined content of halogen, a defined content of non-halogenated double bonds and a defined content of antiagglomeration/vulcanization control agents, exhibit outstanding mechanical and physiological properties, so that they are suitable for the production of tires, particularly tire inner liners, tire sidewalls and tire treads, and for pharmaceutical rubber articles.
