✦ Synopsis

Various carbon blacks were treated in absence of oxygen with azobisisobutyronitrile (AIBN). Samples of non-graphitized carbon blacks (Spheron 6, P33, Sterling FT) and graphitized carbon blacks (Graphon, P33 (HTT)) were studied by ESR before and after the AIBN treatment. The line width, g-factor, and the contributions of localized and conduction carrier spins were determined. The results obtained lead the authors to conclude that in the process of fixation of the products of the thermolysis of the AIBN no radicals are involved.

The spin resonance of H.A.F. and M.P.C. carbon blacks oxidized by ozone or nitric acid has been studied by means of a 9 kMc/s EPR spectrometer. The oxidation treatments create new paramagnetic centers in addition to those already present in these carbon blacks. Since the corresponding spin absorptio
