Abstract

The present invention relates to rubber mixtures consisting of at least one rubber and a specific proportion of a distillation residue from industrial trimethylolpropane production and the use of the rubber mixtures for the production of vulcanisates, especially for the production of highly reinforced, abrasion-resistant mouldings, particularly preferably for the production of tyres exhibiting low rolling resistance and high abrasion resistance.
