Initial oxidation temperature (IOT) is the starting temperature of oxidative exothermal reaction that is observed when the sample is heated at a certain rate under air atmosphere using DSC. It is reported that the IOT figures in a few kinds of rubbers, polyethylene, polypropylene and polyamide66 shift to lower temperatures due to heat degradation. The changes of IOT figures were in line with the changes of residual rate for tensile product measured by tensile test. Here, we report a new method to quantify the degree of degradation of vulcanized rubbers, polyethylene, polypropylene, and polyamide66 by IOT measurement using DSC. The polymers which are applied to this degradation evaluation method included polyethylene, polypropylene, polyamide66, NR, CR, NBR.
