Sorption photodegradation effects

PROBABLE FATE photolysis . C-Cl bond photolysis can occur, not important in aquatic organisms, photooxidation half-life in air 9,24-92.4 hrs, reported to photodegrade in water in spite of the lack of a photoreactive center oxidation-, not an important process hydrolysis . very slow, not important, first-order hydrolytic half-life 207 days, reaction with hydroxyl radicals in atmosphere has a half-life of 2.3 days volatilization may be an important process, however, information is contradictory, volatilization half-life from a model river 6 days, half-life from a model pond considering effects of adsorption 500 days, slow volatilization from water is expected with a rate dependent upon the rate of diffusion through air sorption important for transport to anaerobic sediments biological processes biodegradation is important occurs slowly in aerobic conditions, occurs quickly and extensively in anaerobic conditions... 

Effects of Photodegradation on the Sorption and Transport of Water in Polymers... 

In this present case, we will neglect any effects on sorption due to gross changes in structural/morphologlcal aspects of the polymer. The occurrence of such changes due to photodegradation would be expected to seriously affect other polymer properties of consequence for the application such as adhesion and Impact strength. This, of itself, would suffice to eliminate the material from consideration for the application.
