Abstract
Mainchain photo-scission in a polymer chain often occurs via oxidation. The rate-determinig step of the chain scission is abstraction of a hydrogen atom accompanied by hydroperoxide formation. Solvent and temperature effects in the photochemical chain scission were studied to promote the photodegradation for prevention of plastic waste pollution. Rate of the mainchain scission was dependent on the species of the organo-halogen solvents of the polymer solution for irradiation, but did not increase linearly with rising temperatures.
