##STR00001##

wherein R.sup.1 and R.sup.2 each represent a hydrogen atom, or an alkyl group, alkenyl group or alkynyl group having 1 to 20 carbon atoms, and R.sup.1 and R.sup.2 may be the same as or different from each other; and M.sup.+ represents a sodium, potassium or lithium ion to yield a surface-treated carbon black; and the step (step (ii)) of kneading the resultant surface-treated carbon black, and a rubber. This method for producing a rubber composition for tires allows to yield a tire (vulcanized rubber) low in exothermicity, and give a rubber composition for tires that can be restrained from being lowered in scorch property.

When long chain primary alcohols are into expanded polystyrene (EPS) containing an additive such as carbon black or graphite to give gray EPS, the long chain primary alcohols act as color enhancing agents and generate a darker color as compared with an otherwise identical gray EPS absent the additive.

A composition and method for fabricating graphitic nanocomposites in solid state matrices is presented. The process for fabricating graphitic nanocomposites in solid state matrices may include selecting one or a mixture of specific graphitic nanomaterials. The graphitic nanomaterial(s) may be functionalizing with a moiety similar to the building blocks of the solid state matrices. The functionalized graphitic nanomaterials are mixed with the building blocks of the solid state matrices. The mixture may be cured, which causes in situ formation of the sol-gel solid state matrices that entraps and/or covalently links with the graphitic nanomaterials during the network growing process. This process allows the nanomaterials to be introduced into the matrices homogeneously without forming large aggregations.

Embodiments of the disclosure generally provide compositions and methods involving the production of polyester composite materials that contain covalently bonded carbon black particles. The carbon black particles have surface functional groups that enable the grafting of a polyester, and/or initiate the ring opening of a monomer to create a polyester grown from the surface of the particle.

A composite polymer composition comprising partially crystallized carbon black. The composition exhibits superior thermal transfer properties in plastic formulations. The polymer precursor exhibits excellent rheology when compared to similar compositions comprising traditional carbon blacks. The composite polymers provide for higher loading of more thermally conductive carbon blacks in a variety of composite polymer compositions.

Bio-based materials, e.g., epoxide starting material, a beta-lactone starting material and/or a beta-hydroxy amide starting material, may be used as feedstocks in processes for making and using acrylonitrile and acrylonitrile derivatives to produce, among other products, carbon fibers and carbon black.
