Polymerizable UV absorbers for the UV stabilization of polyesters. I. Design, synthesis and polymerization of a library of UV absorbing monomers [PDF]
Arkivoc, 2021 Poly(ethylene terephthalate) (PET) absorbs strongly in the ultraviolet (UV) region of the EM spectrum (Figure 1), and this can lead to photodegradation of the polymer chains and loss of polymer properties. UV stabilizer additives are normally employed to suppress the UV-induced photodegradation of polyester films, especially for those applications ...

Construction of Nontoxic Polymeric UV-Absorber with Great Resistance to UV-Photoaging. [PDF]
Sci Rep, 2016 AbstractIn this article, we developed a series of new nontoxic polymeric UV-absorbers through covalently attaching a benzophenone derivative onto the main chain of poly(vinyl chloride) (PVC) via mild and quantitative click chemistry. Azide groups were firstly introduced into the backbone of PVC via a nucleophilic reaction without affecting polymeric ...
