Abstract

The invention relates to processing additive mixtures comprising at least one polyol, amide and/or carboxylic acid, optionally auxiliaries for crystallization and at least one organic ammonium salt. Said processing additive mixtures allow the optimization of the vulcanization behavior of rubber mixtures and the properties of vulcanizates obtained by said vulcanization.
