Abstract:
Methods to make a silica elastomer composite with a destabilized dispersion of a never-dried, or as-produced, precipitated silica are described, along with silica elastomer composites made from the methods. The advantages achieved with the methods are further described.

Claim (Index 12):
The method of  claim 1 , further comprising before step 1(a):\n (a) adding an aqueous silicate solution to an aqueous slurry of carbon black particles to form a reaction mixture; (b) adjusting the reaction mixture pH to deposit silica onto the carbon black particles and yield an aqueous slurry of silica coated carbon black particles having an initial ionic concentration; and (c) without drying the reaction mixture to a solids content of greater than 40 wt %, adjusting the aqueous slurry of the silica coated carbon black particles to a solids content of from about 6 wt % to about 35 wt %, further comprising adjusting the initial ionic concentration of the aqueous slurry of precipitated silica to yield a destabilized dispersion of silica coated carbon black particles having an ionic concentration of about 10 mM to about 160 mM.
