Popis:	The effect of different antioxidants and their mixtures on the thermal aging and accelerated weathering of γ -radiation vulcanized EPDM rubber in presence of crosslinking coagent, was investigated. The compounds used were either a synergistic blend of phenolic and phosphite antioxidants, i.e. 1:4 Irganox 1076 : Irgafos 168 or a blend of arylamine and quinoline type antioxidants, i.e. 1:1 IPPD : TMQ , at fixed concentration. Tinuvin 622 LD hindered amine light stabilized (HALS) was also used. The response was evaluated by the tensile strength and elongation at break for irradiated samples after thermal aging at 100°C for 28 days and accelerated weathering (Xenon test) up to 200 h.
