Hindered amine stabilizers thermal aging

Lucarini and co-workers have determined the distribution of the nitroxide radicals in UV-irradiated PP containing a hindered amine stabilizer by one-dimensional (ID) ESRI. The spatial variation of nitroxide intensity in the thicker samples irradiated for longer times was explained by the diflnsion-limited oxidation (DLO) concept. The DLO regime and high oxidation rates lead to narrow penetration depth of oxygen. Recently, Marek et al. ° reported ID ESRI experiments on polystyrene and polypropylene plaques exposed to thermal aging and UV irradiation. [Pg.232]
