Abstract: The degradation of thin films of poly(methyl acrylate) has been studied under 300 mmHg pressure of oxygen in the temperature range 180—250°C. Crosslinking and chain scission occur. Carboxyl, hydroxyl and γ-lactone structures are formed on the polymeric residue. Carbon dioxide comprises ca. 52% of the total evolved volatiles which also include methanol, water and methyl formate. The overall activation energy for volatile formation (weight loss) is 9.8 kcal. Possible oxidation mechanisms are considered and it is concluded that the oxyradical plays an important part.
