Abstract

The invention relates to a process for regenerating sulfur crosslinked rubber vulcanizates to regenerates wherein at least one regenerating agent is used in the regeneration said regenerating agent being selected from the group consisting of dithiophosphoryl polysulfides and/or silanes having a polysulfane group. Regenerates which have been produced by means of the process according to the invention lead to improved or equal rolling resistance indicators and a lower compression set in vulcanized rubber mixtures compared to regenerates known in the prior art.
