Abstract
A process is provided for making a silica masterbatch, that contains silica and solution-made rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition. A process is also provided for making a masterbatch of silica, a solution-made rubber and an emulsion-made rubber.
