Abstract
A process for compounding filler materials and polymers for the preparation of vulcanizable rubber compositions comprises the steps of combining at least one polymer and other compounding ingredients with a filler treated with a liquid in an amount of from about 10 to 60 percent by weight, based upon the combined weight of the liquid and the filler under conditions sufficient to uniformly distribute the filler to form a pre-blend; and mixing the pre-blend until the filler is suitably dispersed throughout the polymer.
