In order to make clear the photodegradation mechanisms of the cyclic olefin polymers, hydrogenated poly (cyclohexadiene-ran-butadiene) (H-CHB) and hydrogenated polystyrene (H-PS), photo-irradiation experiment and analysis of the photodegradation products have been taken place. Under our experimental conditions, we concluded that the polymer degradation occurs similar to the degradation of general polyolefin. Photo-irradiation generates ester bonds, ether bonds, ketones, alcohols and end groups such as carbon-carbon double bonds, aldehydes and chain-end methyl. The photo-irradiation on these cyclic olefin polymers forms the gel mainly.
