ABSTRACT:
The present invention discloses a nanophase carbon black grafted with organic compounds, comprising (a) a first component: 100 parts by weight of original carbon black particles, and (b) a second component: 5-300 parts by weight of grafting organic compounds having or producing free radicals which is grafted onto the surface of the carbon black, wherein the molecular weight of the grafting organic compounds is 100-10000, and the nanophase carbon black has a particle size of 1-100 nm. The invention also discloses the synthesis thereof and articles therefrom.
