Julien Gaume,Julien Gaume,Pascal Wong-Wah-Chung,Agnès Rivaton,Agnès Rivaton,Sandrine Therias,Sandrine Therias,Jean-Luc Gardette,Jean-Luc Gardette +8 more
TL;DR: In this paper, the photochemical behavior of polyvinyl alcohol (PVA) films was studied under UV-visible light irradiation (λ > 300 nm) in accelerated aging conditions representative of natural ageing.

Influence of titanium dioxide pigments on the photodegradation of poly(vinyl chloride)
TL;DR: In this paper, a nanocrystalline rutile powder, anatase white pigment and a photoactive as well as a photostable pigment were examined for their influence on the photodegradation of poly(vinyl chloride), compared to blanc fixe as an inert filler.

Study of discolouring change in PVC, plasticizer and plasticized PVC films
TL;DR: In this article, the authors used UV analysis to study the separate contributions of PVC and plasticizer to discolouring in plasticized and non-plasticized PVC films discolour on photochemical attack.
Journal ArticleDOI
Influence of thermal dehydrochlorination on the photooxidation kinetics of PVC samples
TL;DR: In this paper, a series of PVC samples were thermally dehydrochlorinated under nitrogen and the amount of HCl was monitored and nine samples with increasing quantity of liberated HCl were obtained.

The Effect of Ultraviolet Irradiation on the Physicochemical Properties of Poly(vinyl Chloride) Films Containing Organotin(IV) Complexes as Photostabilizers
TL;DR: Three organotin(IV) complexes containing ciprofloxacin as a ligand were used as additives to inhibit the photodegradation of polyvinyl chloride films upon irradiation with ultraviolet light and the results obtained indicated thatorganotin( IV) complexes stabilized poly(vinylchlor chloride) and the dimethyltin(IV), the most efficient additive.

Thermal decomposition of poly(vinyl chloride)
TL;DR: A free radical mechanism for the dehydrochlorination reaction that appears consistent with the reaction rate data for a three-halves-order reaction is postulated in this paper, and the activation energy is determined.
Journal ArticleDOI
Mechanism of polyvinyl chloride degradation and stabilization
TL;DR: In this article, the authors weigh the results of many workers and to explain the observable changes brought about during degradation by a consistent free radical mechanism, which is not unreasonable to assume the presence of free radicals in polyvinyl chloride.

On the Dehydrochlorination and the Stabilization of Polyvinyl Chloride
Mitsuo Onozuka,Mitsuo Asahina +1 more
TL;DR: In this paper, the thermal stability of polyvinyl chloride (PVC) has been dealt with quite extensively for some decades and there seems to be no remaining problem in processing PVC, because excellent stabilizers have been developed for use with it.
