| Abstract: | It was found that the initial increase in light emission from pre-oxidised polypropylene, measured in a nitrogen atmosphere, is due to decomposition of hydroperoxides in the system. Decomposition is a bimolecular reaction with the probable participation of chemisorbed oxygen. A new initiation reaction step is proposed which contributes to the deterioration of the polymer properties in the induction period of oxidation. |
