ESR measurements under tensile deformation of vulcanized rubber were carried out by the combination of homebuilt stretching machine with commercially available ESR spectrometer. The changes of radical concentrations during tensile deformation were successfully evaluated by this technique. It was found that the destruction and re-construction of crosslinking structure developed in the samples were well correlated with the changes of radical concentrations during tensile deformation. That is, the broken crosslinking structure by stretching was partly recovered in the sample crosslinked by sulfur. On the other hand, such behavior was minor in the sample crosslinked by peroxide.
