  • Process for producing polymer-functionalized filler particles
    Patent number: 8912267
    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.
