Degradability of linear polyolefins under natural weathering (2011, background): “Abiotic degradation only becomes significant after the consumption of the antioxidant additives, and results in the breakdown of the polyolefin molecules into smaller segments and in the incorporation of oxygenated groups, significantly increasing the bioavailability and biodegradability of the poly”
Polymer biodegradation: mechanisms and estimation techniques. (2008, background): “…are added intentionally (i.e. by simple addition or copolymerisation) into the polymer framework to induce a macromolecular degradation by light (e.g. prooxidants agents that can be activated depending on the light intensity and time exposure) (Kounty et al., 2006; Wiles and Scott, 2006).”

An overview of degradable and biodegradable polyolefins (2011, methodology): “7 Figure 1 illustrates some of the products formed as a result of photodegradation of polyethylene.[1] The hydroperoxide group (-CH-OOH) is the primary oxidation product and is both thermally and photolytically unstable.”
