Title: IRON OXIDE IN RUBBER COMPOSITIONS WITH DUAL COUPLING AGENTS
Abstract:
Articles including tire components made of rubber compositions reinforced with an iron oxide reinforcement filler and including a first bifunctional coupling agent and a second bifunctional coupling agent. The first bifunctional coupling agent includes a first alkoxysilyl as a first functional group and a moiety capable of bonding to the iron oxide reinforcement filler as a second functional group. The second bifunctional coupling agent includes a second alkoxysilyl as a third functional group and a moiety capable of bonding with the highly unsaturated diene elastomer as a fourth functional group. The iron oxide may be ferric oxide, iron (II, III) oxide and combinations thereof.
