Scope

When oxygen is present, polymers age in various environments including temperature, radiation, or ultraviolet light, subject to diffusion-limited oxidation, resulting in non-homogeneous aging. These effects make it difficult to understand the aging process and infer accelerated long-term exposure conditions. This section reviews experimental techniques for quantitatively monitoring these effects and provides theoretical equations for assessing their significance.
