DETERIORATION ANALYZING METHOD

摘要

The present invention provides a method of deterioration analysis that enables detailed analysis of the deterioration, especially of the surface, of a polymer material containing at least two diene polymers. The present invention relates to a method of deterioration analysis including: irradiating a polymer material containing at least two diene polymers with high intensity x-rays; and measuring x-ray absorption while varying the energy of the x-rays, to analyze the deterioration of each diene polymer.
