摘要： Disclosed are elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance, lower hysterisis at high temperature and comparable or increased hysterisis at low temperature compared to an elastomer containing an untreated carbon black. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black.

摘要： 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.

摘要： A variety of methods to prepare a polymer composition containing at least one polymer and at least one modified pigment are described. The methods, in part, involve introducing a slurry containing at least one modified pigment into an emulsion or solution polymer prior to dewatering. Other polymer systems can be used including aqueous based polymerizations and solvent-based polymerizations, which can include free radical polymerizations. Other methods involve the formation of a modified pigment in the presence of an emulsion or solution polymer and then recovering the polymer composition containing the modified pigment. Compositions containing at least one modified pigment and the emulsion or solution polymer are also described as well as uses for the polymer compositions of the present invention.
