摘要:
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.

摘要:
This invention relates to a carbon black modified by a two step process in which carbon black is initially treated with functional monomers by an electropolymerization process to form a functionalized carbon black having an initial polymer attached to, of grafted to, the carbon black following which(A) at least one diene monomer, or(B) living anionic catalysis prepared polymer, is introduced to the functionalized carbon black to continue the polymerization, starting from a living end of the initially formed polymer, and thereby form an extended diene-based polymer. By the addition of the diene monomer or the live anionic polymer to form the associated extended diene-based polymer, it is contemplated that the modified carbon black is rendered more compatible with diene-based elastomers. Such modified carbon black may be used, for example, as reinforcement for component(s) of various articles of manufacture, including tires. Accordingly, an article of manufacture is provided, such as for example a tire, having at least one component of a rubber composition which contains such modified carbon black.
