US Classification:

523/215000, 524/495000

Abstract:

This invention relates to preparation of a rubber composition by pre-mixing at least one functionalized carbon black with an organic solvent solution or aqueous emulsion of at least one host elastomer. Functionalized carbon blacks for the purposes of this invention preferably contain a functional moiety on their surface to aid in promoting covalent bonds between the functionalized carbon black and said host polymer. The invention also contemplates the use of such rubber composition, or blend of such rubber composition with at least one additional elastomer and/or rubber compounding ingredient, as a component of an article of manufacture. Such article of manufacture may be, for example, a tire. Such article may also be an industrial product such as, for example, a hose or belt such as a conveyor belt or power transmission belt.

US Classification:

152/209500, 152/905000, 152/537000, 152/547000

Abstract:

This invention relates to a rubber composite made from an elastomer polymerized on the surface of a silanized filler, a rubber composition containing such composite and an article such as for example a tire, which has at least one component comprised of such composition. Such reinforcement is applied by polymerizating a conjugated diene hydrocarbon in the presence of a filler silanized with an alkenyl silane. In particular a silanized reinforcing filler is pre-treated with butyl lithium or peroxide catalyst, preferably with butyl lithium, followed by polymerizing a conjugated diene hydrocarbon in the presence of such treated filler via an anionic or free radical polymerization in an organic solvent. Such pre-formed elastomer composite is also contemplated as well as a rubber composition comprised of a blend of such pre-formed composite and at least one additional elastomer. Such filler may be, for example, precipitated silica, carbon black and/or a modified carbon black. A tire having a component of such composite or rubber composition such as, for example a tread, is also provided.

Abstract:

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.
