  • TIRE COMPRISING A TREAD
    Publication number: 20240326514
    Abstract: The present invention is directed to a tire having a tread, wherein the tread comprises a rubber composition comprising from 80 phr to 100 phr of one or more solution-polymerized styrene butadiene rubbers; from 80 phr to 200 phr of filler comprising at least 40 phr of carbon black; from 10 phr to 100 phr of one or more liquid diene-based polymers; and from 10 phr to 80 phr of a terpene resin.

  • 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.
