It was observed that light is emitted upon polymer oxidation; intensity of light is proportional to oxygen concentration on the surface and presence of an antioxidant effects the emission of light. A linear relationship was found to exist between integrated light intensity and the number of carbonyl atoms formed. In addition concentration of antioxidants present and their synergistic effects can be measured by this method.
