The grafting of polymers onto a carbon black surface based on the trapping of polymer radicals by polycondensed aromatic rings of the surface was investigated. It was found that polymer radicals formed by the thermal decomposition of azo-polymer, peroxy-polymer and 2,2,6,6-tetramethylpiperidinyl-1-o
Alcohols between 1-18 carbon atoms, were grafted onto the surface of carbon blacks. The behavior of these grafts was studied essentially by two techniques: measurement of adsorption isotherms of water and liquid flow adsorption microcalorimetry. The results show that the surface properties of the gr
