Abstract

Rubber mixtures prepared from at least one styrene/butadiene rubber gel and at least one rubber which contains double bonds and optionally further fillers and rubber auxiliary substances are in particular suitable for the preparation of vulcanisates having unusually high damping at temperatures of from -20 to +20°C as well as unusually low damping at temperatures of from 40 to 80°C. The rubber mixtures may therefore be used, for example, to manufacture vehicle tyres which grip in the wet and have low rolling resistance.
