Abstract

Polymer additive granules are formed by combining together (i) a silica powder and (ii) a fatty component, to form a preblend; combining the preblend with at least one polymer additive, to form a powder blend; combining a processing solvent and the powder blend to form a mixture; and granulating the mixture to form granules.
