The object of the invention was to provide novel stellate rubbers which have a tan delta curve having the broadest possible vibration- attenuation range. …<??>Novel, unsaturated, elastomeric, asymmetrically coupled block copolymers of the general formula (A)n-X-(B)m have now been found which are obtainable by two-pot polymerisation and subsequent coupling. …<??>The novel block copolymers are suitable for the production of high-quality tyre components. …<IMAGE>… |
