Abstract:
Thermal decomposition of pure poly(methyl methacrylate) (PMMA) and its composition with Ñ$_{60}$ fullerene before and after UV irradiation has been studied by thermodesorption mass spectrometry (TDMS). It is established that low-temperature depolymerization of UV-irradiated PMMA is suppressed in its composition with Ñ$_{60}$. Possible molecular stabilization mechanisms are discussed.
