A reduced order kmetics model is proposed for the corxosron of polyethylene in bleach solution. Hypochlorous add (HOC1) is considered as the oxidizing agent which is formed from the hydrolysis of bleach. The model simulates the diffusion of HOC1 into the non-polar polymer matrix followed by its dissociation into radicals The reaction between the radicals and the polymer is phenomenologically modeled using an ordinary differential equation. The model is suitable for coupling with mechanical models for life-time analyses of polymers members under mechanical loading and exposure to corrosion. The model captures the effect of the chain oxidation process which causes the accelerated aging of the polymer.
