    摘要： This invention relates to preparation of an elastomer which contains a dispersion of silica reinforcement by forming a silica reinforcement in situ within an unvulcanized elastomer host, the resulting elastomer/filler composite and tire having component which contains such reinforced elastomer. The invention includes a rubber composition of at least two elastomers wherein one of said elastomers is a pre-formed composite of elastomer/in situ formed silica reinforcement. A tire having a component of such rubber composition, particularly a tire tread, is specifically contemplated.
