Abstract: The dynamics of thermoinduced defect formation and the photoluminescent properties of a poly(methyl methacrylate)-fullerene (PMMA-С$_{60}$) composite have been studied using a combination of spectroscopic techniques. Quantum-chemical calculations with implicit allowance for the presence of oxygen have been performed for a MMA-С$_{60}$ model complex. The generation of defects and the quenching of photoluminescence, which take place in the same temperature interval where the macromolecules exhibit low-temperature depolymerization in the presence of С$_{60}$, can be precursors of the depolymerization process.
