Claim Text:
1. A method for manufacturing a functionalized silica product, the method comprising the steps of: providing a hydrophobated high surface area silica in a rotary dryer; introducing a polymer cement to the rotary dryer, the polymer cement having a solution polymer at least partially dissolved in a solvent, wherein the solution polymer is a solution styrene butadiene rubber; and heating the rotary dryer to drive off the solvent, wherein a functionalized silica product is formed with particles of the hydrophobated silica having a coating of the solution polymer, wherein a ratio of the hydrophobated silica to the solution polymer is from about 0.3/1 to about 100/1, wherein the hydrophobated silica includes a high surface area silica having a BET specific surface area greater than about 200 m
