TL;DR: In this paper, the authors present a review of the approaches to predict the lifetime of polymers such as polyolefins, and the similarities in mechanism provide real prospects for the prediction of the safe service lifetime of a biodegradable polymer as a structural material.

TL;DR: Mechanisms of biodegradation occurred at the polymer surface and the rate was governed by both biodeterioration and depolymerisation, which were shown to be controlled by a combination of copolymer composition, crystallinity, microstructure and surface morphology.

TL;DR: In this article, a photo-sensitive linear low density polyethylene (LLDPE) + 1% nano-titania (as the anatase/rutile mixed phase P25) was found to have a higher rate of degradation when buried outdoors in soil than when buried under laboratory conditions: the elongation at break fell from 900% to 70% in one month in the field while similar changes required 6 months in the laboratory.

TL;DR: In this article, a linear low density polyethylene (LLDPE) films containing the combination of pro-oxidants titanium (IV) dioxide (TiO2) with either cobalt (II) stearate (CoSt) or iron (II)-stearate(FeSt) have been evaluated under accelerated photo-and thermo-oxyidative conditions as well as on outdoor weathering LLDPE.
