The present invention relates to a process for producing rubber mixtures, to the rubber mixtures obtainable by the process, to the use of rubber mixtures for producing tires or semi-finished products for tires and crosslinked elastomer molded articles which are obtained by vulcanization of the rubber mixtures produced according to the present invention.

Process for producing rubber mixtures

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.

Rubber mixtures containing trimethylopropane distillation residues

Disclosed herein are stabilized dithiophosphoric acid polysulphides of the formula (I) ##STR1## in which R is a C.sub.1 -C.sub.20 alkyl, cycloalkyl, aryl or aralkyl residue and

Stabilised dithiophosphoric acid polysulphides

A masticating agent for rubber consists of tallow fatty acid with an addition of 0.1 to 3% by weight (based on the masticating agent) of a 16-membered, metal-containing ring compound.
