摘要:
The invention relates to an elastomer/reinforcing filler composite in which said elastomer contains a dispersion therein of said reinforcing filler wherein said composite is prepared by forming said filler reinforcement in situ within the elastomer host. Such in-situ formation of reinforcement filler is created by a condensation reaction of a filler precursor within a solvent solution of a diene hydrocarbon based elastomer and with the aid of a phase transfer agent and a condensation reaction promoter. The invention further relates to a tire having at least one component comprised of the resulting elastomer/filler composite. The invention includes a rubber composition of at least two elastomers wherein one of said elastomers is a said pre-formed composite of said elastomer/filler reinforcement. A tire having a component of such rubber composition, particularly a tire tread, is specifically contemplated.

摘要:
This invention relates to the preparation of an elastomer which contains a dispersion of a reinforcing system formed in situ within an elastomer host by the interaction of a telechelic hydroxy and/or alkoxy terminated polysiloxane and a reticulating agent having a moiety comprised of at least two alkoxy groups. The invention further includes a rubber composition of at least two elastomers wherein one of said elastomers is a pre-formed composite of elastomer and the in situ formed reinforcement system. A tire having a component of such rubber composition, particularly a tire tread, is specifically contemplated.
