TLDR
A hindered piperidine stabiliser, bis{2,2,6,6-tetramethyl-4-piperidinyl}-sebacate, has been found to inhibit the photo-sensitising effect of anthraquinone in polypropylene on flash photolysis in n -hexane solution transient formation due to the semi-quinone radical (AH·) at 370 nm and subsequent formation of the hydroquinone (9,10-dihydroxyanthracene (AH 2 ) were found to be effectively inhibited

Degradation and stabilisation of styrene–ethylene–butadiene–styrene (SEBS) block copolymer

TL;DR: The degradation of hydrogenated poly[styrene b -butadiene- b -styrene] has been studied using a variety of analytical and spectroscopic methods including thermal analysis, UV, luminescence and FTIR spectroscopy coupled with crosslinking and hydroperoxide analysis in order to understand the nature of the processes involved as mentioned in this paper.

Some aspects of stabilization of polymers against light

TL;DR: In this paper, different mechanisms for the protection of polymers against photodegradation are discussed, and evidence is presented that this rapid nonradiative deactivation cannot be explained very satisfactorily by a simple 'enol-keto'-equilibrium in the first excited singlet state only.
