    摘要： A method of preparing a rubber composition is disclosed. The method comprises
    (A) preparing a preparatory rubber composition in the absence of sulfur comprising the steps of:
    (1) preparing at least two individual and separate uncured rubber masterbatches, each comprising blending and intimately dispersing a reinforcing filler comprising of at least one of carbon black and silica in elastomer(s) comprising of at least one conjugated diene-based elastomer, and
    (2) blending the uncured rubber masterbatches together with a silica coupling agent to form a reactive rubber composition by:
    (a) blending at least two of the masterbatches together for which a silica coupling agent is blended therewith, following which the remainder of the masterbatches are blended therewith, or
    (b) blending at least two of said masterbatches together in the presence of a silica coupling agent following which the remainder of the masterbatches are blended therewith, and

    (B) preparing a productive rubber composition by blending a rubber cure package comprising sulfur and at least one sulfur vulcanization accelerator with the reactive rubber composition.
