Abstract
Thermal oxidative aging is limiting the life time of rubber products. Beside environmental factors the microstructure of used polymers, the crosslinking, fillers and additives are influencing components, especially several antioxidants, where their efficiency is of high interest. From the measurements using NMR-relaxation, CL and physical testing, it is to conclude, that the concentration of the C=C-double bonds in the main chain of the polymer has a significant quantitative influence on the thermal oxidative stability. The crosslink density has nearly no effect in the used SBR-systems. The investigations of the efficiency of antioxidants in IR and SBR with different micro structures results in the sequence DPPD > 6PPD > 77PD.
