摘要:
The rubber mixtures according to the invention, containing at least one rubber, a vulcanizing agent, a filler, optionally other rubber additives and at least one reinforcing additive of the formula ##STR1## are used for the production of vulcanized rubbers, from which in particular tires can be produced having a low rolling resistance combined with a good wet skid resistance and a high abrasion resistance.
