“…In both cases, it was found that the PVC antimicrobial efficiency has been enhanced, for example, the addition of the amide derivatives of ethylene glycol‐bis (2‐aminoethylether)‐ N,N,N′,N′ ‐tetraacetic acid (EGTA) as photostabilizers using the casting technique has augmented the biological activities of PVC . Rabie and coworkers have demonstrated that PVC‐pyrimidinethione adducts, prepared by chemical substitution of the PVC chlorine atom with pyrimidinethione derivatives have shown promising antimicrobial activities compared to nonmodified PVC .…”

Polyvinyl chloride (PVC) was modified via substitution reaction with 2-aminothiazole and ethyl 2-aminothiazole-4-carboxylate separately in the absence and in presence of silver (AgNPs) or copper (CuNPs) nanoparticles, using metal salts as precursors, in 3% (w/w) with respect to PVC. The functionalized PVCnanocomposites have been characterized via FTIR, 1 HNMR spectroscopic analyses, in addition to the morphological investigation such as scanning (SEM) and transmission electron microscopy (TEM). Spectral data confirmed the introduction of the thiazole (ester) to the PVC backbone. TEM analysis showed that the sizes of the AgNPs and CuNPs have fallen in the range of 10-30 nm and 30-50 nm for the prepared nanocomposites, respectively. Evaluating the photostability of modified nanocomposites was estimated by following the extent of discoloration for UV-irradiated samples colorimetrically in accordance with the irradiation time. The antimicrobial activity of the modified nanocomposites was explored against three Gram+ve bacteria (Bacillus subtilis, Staphylococcus aureus, and Streptococcus faecalis), three Gram-ve bacteria (Escherichia coli, Neisseria gonorrhoeae, and Pseudomonas aeruginosa), and two fungi (Candida albicans and Aspergillus flavus). Aminothiazole (ester)-functionalized PVC exhibited significant antimicrobial efficiencies against the investigated pathogens. However, incorporation of AgNPs or CuNPs to the modified PVC enhanced their inhibitory effect against the microorganisms under investigation. J. VINYL ADDIT. TECHNOL., 25:E137-E146, 2019.

“…Photostabilizing efficiency of the modified PVC is determined by measuring the changes that occurred in the molecular weights of modified samples after UV irradiation using the gel permeation chromatography, GPC technique. The extent of discoloration of the photodegraded modified PVC is lower than that of the blank one, and that stabilized with the reference UV absorber phenyl salicylate .…”

Some pyridopyrimidine derivatives with high biological activity have been investigated as photostabilizers for rigid Poly(vinyl chloride) (PVC). Their stabilizing efficiencies were evaluated by determining the percentage of weight loss, the amount of formed gel, as well as the intrinsic viscosities, of the photodegraded PVC. The extent of discoloration of the photodegraded polymer was also evaluated. The antimicrobial activities of PVC was evaluated in absence and in presence of the investigated materials. The applied materials reduced the loss in weight that resulted from HCl evolution during photodegradation. Both viscosity and gel content measurements showed also a decrease in their values during the degradation process. The extent of discoloration was also improved. The results have proved a greater stabilizing efficiencies of the antimicrobial pyridopyrimidine derivatives than that of the industrial UV absorber, phenyl salicylate. Photostabilized samples of PVC exhibited good antimicrobial activities against some types of bacteria and fungi. A radical mechanism was proposed to account for the stabilizing action of the investigated products. J. VINYL ADDIT. TECHNOL.,

Poly(vinyl chloride), PVC, stands as one of the best polymer candidates as far as polymeric materials are strongly sought for in our today's life. Functionalization of poly(vinyl chloride) (PVC) remains an appropriate way to fashion materials for specific applications. Molecules of different functionalities and sizes, up to macromolecules, were affixed to PVC matrix. Graft polymerization led to functionalized PVC with several properties for different applications. Some covalently modified PVCs, mainly with heteroatom-containing and cyclic molecules, proved to be biologically active and efficient scaffolds for enzyme/protein immobilization. Suitable functionalizations of PVC even ensured the effectiveness of the polymers as separative, ion-selective electrode, and fuel cell membranes. Some modifying agents incorporated in PVC made the polymeric materials convenient and reliable for solar cells design. Reactions of PVC with metal chelating molecules engendered PVC-metal complexes that were efficient polymer-supported catalysts for Heck, Sonogashira, and Suzuki-Miyaura coupling reactions. Heavy metal sorbents were also made by tailored functionalization of PVC. Modifications of PVC with allotropic carbon nanoparticles, including fullerene C60, carbon nanotubes, and graphene and their applications in the nanocomposites making are herein discussed. The newly emerged "click chemistry" and "living controlled radical polymerization, LCRP" were exploited in the functionalization of poly(vinyl chloride).
