Method for producing additive carbon black

A method for producing a surface-treated additive carbon black comprising combining carbon black with an amine antidegradant, wherein the combination occurs substantially free of a solvent or carrier.

A method of producing an additive carbon black comprising combining carbon black with a neat amine antidegradant, wherein the carbon black has a surface area of less than or equal to 130 m2/g.

A method of producing an additive carbon black comprising combining carbon black with a substantially neat amine antidegradant, wherein the carbon black has a surface area of less than or equal to 130 m2/g and the amine antidegradant is naphthylamine, naphthylamine derivative, diphenylamine, diphenylamine derivative, p-phenylenediamine, p-phenylenediamine derivative, other amine compound, or a mixture thereof.

A method of combining a polymer and a carbon black treated with a solvent-free naphthylamine, naphthylamine derivative, diphenylamine, diphenylamine derivative, p-phenylenediamine, p-phenylenediamine derivative, other amine compound or mixtures thereof, in a first stage comprising

• adding to a polymer a first quantity of the treated carbon black;
• and,
• adding to said polymer a second quantity of the treated carbon black with oil or in an oil mixture, wherein a masterbatch is made during the first stage.

A method for combining a naphthylamine treated, naphthylamine derivative treated, diphenylamine treated, diphenylamine derivative treated, p-phenylenediamine treated, p-phenylenediamine derivative treated or other amine compound, substantially free of solvent, surface-treated carbon black with a polymer, comprising adding to a polymer a mixture comprising the surface-treated carbon black and oil and mixing.

An article-of-manufacture comprising a surface-treated additive carbon black produced by combining an amine antidegradant with carbon black in the absence of a solvent or carrier.
