“…To solve the problem of the high costs of bio-based raw materials used in the production of plasticizers, the use of waste cooking oil as a bio source was proposed by Zheng et al and others [ 81 , 98 , 99 ]. Waste cooking oil 2-ethylhexyl esters (WCOEtHEs) were obtained from waste cooking oil methyl esters (WCOMEs).…”

This paper reviews the current trends in replacing commonly used plasticizers in poly(vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency. Novel plasticizers have been divided into three groups depending on the replacement strategy, i.e., total replacement, partial replacement, and internal plasticizers. Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer performance in comparison to PVC plasticized with conventionally applied bis(2-ethylhexyl) phthalate, di-n-octyl phthalate, bis(2-ethylhexyl) terephthalate and di-n-octyl terephthalate. Among a variety of newly developed plasticizers, we have indicated those presenting excellent migration resistance and advantageous mechanical properties, as well as those derived from natural sources. A separate chapter has been dedicated to the description of a synergistic effect of a mixture of two plasticizers, primary and secondary, that benefits in migration suppression when secondary plasticizer is added to PVC blend.

“…It has been reported that because of chlorine's high electronegativity in PVC molecules, the hydrogen atom on the same carbon atom as chlorine atoms easily forms hydrogen bonds with polar groups of the plasticizer. These intermolecular interactions can enhance the stability of C─Cl bond, thus suppressing the dehydrochlorination degradation step 25,29 . Therefore, the observed improved thermal stability was explained in terms of ketal groups forming more hydrogen bonds with PVC than ketone groups, thus enhancing the stability of C─Cl bonds (Figure 4).…”

“…Therefore, to find a substitute for conventional DOP with comparable performance, nontoxic plasticizers based on sustainable resources have attracted a lot of attention in recent years, 16–18 with biobased resources receiving much attention due to their nontoxic and sustainable characteristics 19–21 . As a result, numerous alternative plasticizers derived from biobased resources, have been developed, including fatty acid esters, 22,23 tung oil, 24,25 soybean oil, 26,27 isosorbide, 28,29 castor oil, 30–32 and tartaric acid 33 . Moreover, some biobased plasticizers have been developed and commercialized.…”

Two castor oil acid esters containing a ketal or ketone group (KCL or CL), as alternative plasticizers for poly(vinyl chloride) (PVC), were prepared. The structures were confirmed by 1H NMR and FTIR spectroscopies. The effects of the presence of a ketal or ketone group in these compounds on PVC plasticization were examined. The DMA and SEM results showed that both plasticizers were miscible with PVC and exhibited excellent plasticizing properties, compared to those of dioctyl phthalate (DOP). The PVC plasticized by KCL displayed a lower Tg value of 20.6°C, which was lower than that of PVC plasticized with DOP (22.3°C) and PVC plasticized with CL (40.5°C). Tensile tests indicated that PVC plasticized using KCL showed a 37% higher of elongation at break than PVC plasticized by CL and 30% higher than PVC plasticized by DOP. The plasticizing mechanism was also investigated. Moreover, exudation, volatility, and extraction tests, along with TGA indicated that the presence of ketal groups effectively improved the migration resistance of plasticizer and the thermal stability of PVC blends. Taken together, introducing ketal groups into plasticizer might be an effective strategy for improving its plasticizing efficiency.

“…37,38 The second rapid weightlessness formed at around 420-500 C, which caused by the degradation of polyene into olefins. 39 The thermal degradation rate of the PVC samples at each stage could be more clearly observed from their DTG curves in Figure 6b.…”

A series of bio‐based diester plasticizers with various alkyl chain asymmetry and the same molecular weight were designed and synthesized, using renewable 5‐hydroxymethyl‐2‐furancarboxylic acid (HFCA) as the raw material. The chemical structures of the HFCA‐based plasticizers were characterized by Fourier transform infrared and nuclear magnetic resonance (1H NMR and 13C NMR). Besides, the influence of alkyl chain asymmetry on plasticization properties of the HFCA‐based plasticizers in poly(vinyl chloride) (PVC) blends was also investigated. It was found that increasing the alkyl chain asymmetry of the diester plasticizer and keeping the molecular weight unchanged simultaneously could further improve its plasticizing efficiency, without sacrificing its volatility resistance and exudation resistance. The results showed that this study provided a new approach for further optimizing the overall properties of the asymmetric diester plasticizers.
