    Abstract: A method of making an aggregate comprising at least a carbon phase and a silicon-containing species phase is disclosed. The method involves introducing a first feedstock into a first stage of a multi-stage reactor, and introducing a second feedstock into the reactor at a location downstream of the first stage. The first and second feedstock comprise a carbon black-yielding feedstock, and at least one feedstock also comprises a silicon-containing compound. The reactor is operated at a sufficient temperature to decompose the silicon-containing compound and to pyrolize the carbon black-yielding feedstock. An additional method is disclosed which involves making an aggregate comprising a carbon phase and a silicon-containing species phase using multi-stage reactor having at least the stages for introducing a feedstock, wherein at least one of the feedstocks comprises a carbon black-yielding feedstock and wherein at least one of the feedstock comprises a silicon-containing compound. Besides producing the aggregate comprising a carbon phase and a silicon-containing species phase, silica and/or carbon black may also result from the processes of the present invention. A further method is disclosed which involves making an aggregate comprising a carbon phase and a metal-containing species phase using a multi-stage reactor having at least two stages for introducing feedstocks, wherein at least one of the feedstocks comprises a carbon black-yielding feedstock and where at least one of the feedstocks comprises a metal-containing compound. The aggregates of the present invention when incorporated into elastomeric compositions preferably lead to improved wet skid resistance properties.

    Abstract: Disclosed are elastomeric compositions including an elastomer and an aggregate comprising a carbon phase and a metal-containing species phase, optionally including a coupling agent. Also disclosed is an aggregate comprising a carbon phase and a metal-containing species phase. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compositions incorporating an elastomer and the aggregate are also disclosed. Also disclosed are methods for preparing elastomers compounded with the aggregate, and methods of improving various properties of elastomeric compositions, such as abrasion resistance, hysteresis, wet skid resistance, and/or wet traction.
