A polymer coated modified carbon product is described wherein the polymer at least partially coats a 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.

L'invention concerne un produit carbone modifié revêtu de polymère. Le polymère couvre au moins partiellement le produit carbone modifié. Ledit produit a, de préférence, au moins un groupe organique fixé au produit carbone, le groupe organique étant, de préférence, substitué par un groupe ionique, ionisable ou polaire pour la préparation d'un milieu à base polaire ou aqueuse. L'invention traite également de procédés de production du produit carbone modifié revêtu de polymère, tels que les procédés de polymérisation à base aqueuse ou sans solvant, de procédés de polymérisation à base de solvant organique, ou de procédés de revêtement à l'aide de solution. L'invention concerne également des produits polymères et des mélanges maîtres contenant les produits carbones modifiés revêtus de polymère, ainsi que des procédés destinés à améliorer des propriétés telles que les caractéristiques d'impact et les caractéristiques de traction.
