Abstract

Alkyd resin modified with waterborn phenolic component was loaded with different loadings of titania nanoparticles (2, 5 and 10 wt %). These systems were subjected to accelerated degradation by -irradiation, when the formation of radicals occurred. The highest studied concentration of TiO2 brings about the most efficient stabilization effect. The isothermal and nonisothermal chemiluminescence procedures have proved the improvement in material durability by the adsorption of radicals on the large surface of filler nanoparticles..
