Abstract
Elastomeric compositions contain at least one elastomer and a polymer coated modified carbon product wherein the polymer at least partially coats the modified carbon product. The modified product preferably has at least one organic group attached to the carbon product and the organic group is preferably substituted with an ionic, ionizable, or polar group for preparation in polar or aqueous based media. Methods of making the polymer coated modified carbon product are also described, such as by aqueous-based or solvent free polymerization methods, organic solvent based polymerization methods, or solution coating methods. Polymeric products and masterbatches containing the polymer coated modified carbon products are also described as well as methods to improve properties such as impact properties and tensile properties.
