Weathering Degradation of Polymers
TL;DR: The structures of polymers based on several kinds of bonds are always subjected to the modifications, when they are placed in specific conditions as discussed by the authors, and the activities where polymer items are involved depend entirely on the material strength to the energy transfer from the surrounding space.

Role of metals and metal-deactivators in polymer degradation
TL;DR: In this article, the role of metal compounds in the degradation of polyolefins has been investigated and some typical examples of degradation by metallic compounds, mostly commercial pigments and transition metal compounds of stearic acid and acetylacetone, in typical commercial polymers are discussed.

Chemiluminescence from peroxides in polypropylene. Part I: Relation of luminescence to peroxide content
TL;DR: The weak chemiluminescence observed when partially oxidised samples of polypropylene are heated in an inert atmosphere has been studied as a function of oxidation as discussed by the authors, and the integrated luminescence is shown to be proportional to titratable peroxides in the early stages of oxidation but the relation is curved at higher oxidation levels.

DTA for control of stability in polyolefin wire and cable compounds
TL;DR: Differential thermal analysis offers a convenient and rapid way of determining stabilization levels in polyolefin compositions as discussed by the authors, however, because the chemistry of the polymer system at these temperatures may be quite different from that at normal use temperatures, judgment must be exercised in attempting to extrapolate high temperature data.
