抄録

Electron spin resonance of three kinds of carbon blacks, i.e. channel black (EP), furnace black (HAF) and thermal black (FT) have been studied in connection with the mechanism of the strengthen effect on rubber.<br>1) Each carbon black has a different line width and forms. The result shows that the structure of the free radical are different from each other. The concentration of the free radicals is ordered as follows:<br>EPC<FT<HAF<br>3) When they were heated in vacuo, the form of the absorption of HAF and FT were not varied, but that of EPC became very sharp and asymmetry.<br>4) In order to increase the free radicals of carbon black, Co-60 gamma-rays was irradiated on them, but little effect was observed.
