Abstract

Polymers are susceptible to altered chemistry from UV radiation. The absorption of UV photons can promote breakage of important functional groups and structural bonds, such as C=C and C=O [1]. When an organic molecule absorbs UV radiation, it will be excited into higher energy states and possibly dissociate bonds. Dissociated radical species can then participate in additional reactions. Changes in chemistry may affect optical properties, which can have serious effects for polymers used in optical systems.
