Abstract: A process for regenerating sulfur-crosslinked rubber vulcanizates to regenerates, wherein at least one regenerating agent is used in the regeneration. The regenerating agent is 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 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.

Abstract: A process for producing polymer-functionalized filler particles and polymer-functionalized filler particles obtained by this process. The polymer-functionalized filler particles are used as additives for rubber mixtures. The polymers for functionalizing the filler particles are obtained in-situ starting from filler particles having a surface-bound RAFT agent. The binding of silyl-bearing RAFT agents and of Diels-Alder RAFT agents occurs via the R-group and the subsequent RAFT polymerization proceeds via a reactive site of the RAFT agent.
