... temperatures. The antioxidant depletion times are reported for temperatures between 20 and 95°C. The solubility of the antioxidant and stabilizer packages, the oxidation by-products, and their susceptibility to hydrolysis are discussed. After 28 months of incubation, no oxidative degradation was observed...

The antioxidant depletion rates obtained from standard oxidative induction time (Std-OIT) tests were consistently lower than that obtained from high-pressure oxidative induction time (HP-OIT) tests...

...R.P. Krushelnitzky; R.W.I. Brachman ABSTRACT: Antioxidant depletion rates are reported for samples of one particular high-density polyethylene pipe when immersed in air and a synthetic municipal solid waste leachate, obtained by measuring the oxidative induction time (OIT) at temperatures of 22°C...

... the geomembrane. Arrhenius modelling gave activation energies for antioxidant depletion of between 62.5 and 64.0 kJ/mol. The small difference in activation energies implies that the four leachates examined are similar in terms of antioxidant depletion rate. There was no evident effect of the difference...
