As the polymer industry evolved, considerable effort was made to understand the degradation processes of high polymers during weathering and ways were found to inhibit or at least retard their chemical modification and loss of their physical and mechanical properties. Weathering is particularly severe for polymers because it combines the photophysical and photochemical effects of ultraviolet radiation with oxidative and hydrolytic effects of the outdoor environment. This article discusses photo… 
P Photostabilization of Polymers
The photodegradation of polymers has been studied from the early years due to its commercial production. Most plastics are affected by exposure to sunlight in conjunction with other natural
Factors Influencing the Photochemical Behavior of Multicomponent Polymeric Materials
The study of photo-degradation and stabilization of polymers has an extremely importance from academic, economic and environmental point of view and a better understanding of the mechanism of
Photodegradation and photostabilization of polymers, especially polystyrene: review
TLDR
Almost all synthetic polymers require stabilization against adverse environmental effects, and two aspects of degradation are of particular importance: Storage conditions, and Addition of appropriate stabilizers.
Photostability of plasma polymerized γ-terpinene thin films for encapsulation of OPV
TLDR
It is demonstrated that an encapsulating layer of plasma polymerized γ-terpinene reduces degradation-related loss in conversion efficiency in PCPDTBT:PC70BM solar cells under ambient operating conditions.
EVALUATION OF SEVERAL COMMERCIAL POLYMERS AS SUPPORT FOR TiO2 IN PHOTOCATALYTIC APPLICATIONS
This work is aimed to select the best synthetic polymers available in the market with high transmittance in the TiO2 activation range that can be coated with the semiconductor and withstand the
Revising the mechanism of polymer autooxidation.
TLDR
It is shown that it is the presence of structural defects, such as terminal or internal double bonds, formed either during polymerisation or in the degradation process itself, that is responsible for the autooxidation of most polyesters and most polyalkenes.
