METHOD OF MAKING HYDROPHOBATED SILICA AND USE OF SUCH A SILICA

A method for making a hydrophobated or pre-hydrophobated silica in an aqueous medium is disclosed. The method comprises: (1) dispersing silica, a phase transfer agent, and a silica coupling agent into water to make an aqueous silica slurry; (2) allowing the silica coupling agent to react with the si...

description	A method for making a hydrophobated or pre-hydrophobated silica in an aqueous medium is disclosed. The method comprises: (1) dispersing silica, a phase transfer agent, and a silica coupling agent into water to make an aqueous silica slurry; (2) allowing the silica coupling agent to react with the silica to produce the hydrophobated or pre-hydrophobated silica; and (3) recovering the pre-hydrophobated silica from the aqueous silica slurry. The silica may be used in a tire, preferably a tire tread.
