Abstract

Half wave oxidation potentials of antioxidants and some chemicals which belonged to amine derivatives were measured by using polarography. The potentials were related to the effects of these chemicals as antioxidants, and to the highest occupied energy level.<br>As the results, it was found that (1) chemicals were most effective as antioxidants when the half wave oxidation potentials existed in 0.3 to 0.5 volt, and that (2) the lower the potentials of anilin derivatives were, the more effective the chemicals were exponentially, and that (3) their potentials related linealy to the highest occupied energy levels of them.<br>From these results, electrons in amine derivatives were assumed to have an important point in these reactions. The first reaction between oxidized rubber molecule and antioxidants of amine derivatives may be electron transfer from the latter to the former.
