Abstract
The goal of this paper is the qualification of natural antioxidants (rosemary extract, capsaicin,
quercetin or oleanolic acid) playing as antioxidant. The stabilization activities were investigated in
several formulations based on ethylene-propylene-diene-terpolymer (EPDM) in pristine state or after
-irradiation, when the accelerated degradation scission of polymer macromolecules followed by the
mitigation of oxidation. Three evaluation procedures: chemiluminescence, FTIR spectroscopy and
thermal analysis were applied for the characterization of the stability contribution. The durability of
studied EPDM formulations is discussed for the assessment of material life. The improved behavior
of structured hybrids useful for the optimization application regimes is essentially based on the
antioxidant properties of polyphenolic components in the cases of natural antioxidant
