Review of polymer oxidation and its relationship with materials performance and lifetime prediction
TL;DR: In this article, the authors present a brief status report on the important aspects of polymer oxidation and focus on the complexity of thermally accelerated polymer aging phenomena, the importance of DLO, property correlations, kinetic models, TGA approaches, and a framework for predictive aging models are briefly discussed.

Correlation of Chemical and Mechanical Property Changes During Oxidative Degradation of Neoprene
TL;DR: In this paper, the thermal degradation of a commercial, stabilized, unfilled neoprene (chloroprene) rubber was investigated at temperatures up to 140 C. Important heterogeneous oxidation effects were observed at the various temperatures investigated using infrared micro-spectroscopy and modulus profiling.

Validation of improved methods for predicting long-term elastomeric seal lifetimes from compression stress-relaxation and oxygen consumption techniques.
TL;DR: In this paper, the authors describe modifications that allow the force measurements to be made isothermally and show that such measurements lead to more accurate estimates of sealing force decay, and use conventional Arrhenius analysis and linear extrapolation of the high-temperature compression stress-relaxation (CSR) results for two commercial butyl o-ring materials to show that Butyl-B is predicted to have approximately three times longer lifetime at room temperature (23°C).

Oxidation profiles of thermally aged nitrile rubber
TL;DR: In this paper, the thermal degradation of a commercial, stabilized, unfilled nitrile (Buna-N) rubber material was investigated at temperatures in the range 85-140 °C.
