Notes:
Fourier self-deconvolution of the carbonyl peak present in the infrared spectrum of oxidized polyethylene has successfully resolved the peak into its components. Three strong bands at 1713, 1719, and 1723 cm-1, together with a number of weaker features, are detected. In agreement with previous work, the 1719 and 1723 cm-1 bands are assigned to saturated ketones and saturated carboxylic acids, respectively. A new band is also observed at 1697 cm-1. The relative amounts of the components differ between high-density, linear low-density, and low-density polyethylene. The 1697 cm-1 band is very dependent on the type of polyethylene; it is strong in high-density, weak in linear low-density, and very weak in low-density polyethylene.
