“…It was observed from the TGA curves that all the samples are thermally stable in nitrogen gas below 190 C and mainly displayed three-stage thermal degradation above this temperature. 43,44 Furthermore, the TGA characteristic temperatures of PVC lms are illustrated in Table 3, including the onset, 10% and 50%, weight loss temperatures (T 10 and T 50 ) for the degradation. 36 In the second stage of degradation (about 340-420 C), the weight was almost stable, which may be associated with the formation of aromatic compounds by the cyclization of conjugated polyene sequences.…”

A novel plasticizer derived from cardanol, and epoxied cardanol glycidyl ether (ECGE), was synthesized and characterized by 1 H-NMR and 13 C-NMR. The effects of ECGE combined with the commercial plasticizer dioctyl phthalate (DOP), in soft poly(vinyl chloride) (PVC) films, were studied. The mechanical properties of PVC films showed both tensile strength and percent elongation increases with increasing ECGE content. Thermogravimetric analysis (TGA) was performed to characterize the thermal stabilities of the plasticized samples and showed the stability of films increased on increasing the content of ECGE. The properties of volatility, extraction, and exudation resistance of plasticizers were tested and analysis by means of solubility parameters as reported in the literature suggests the ECGE has similar or higher stability for these properties than DOP. FTIR analysis of the films also revealed that ECGE interacted with PVC. Due to its inherent chemical backbone and the modified epoxy groups, ECGE properly balanced the properties and improved the performance of PVC films compared with the neat DOP plasticizer.

Epoxidized castor oil-based diglycidyl-phthalate (ECODP) was synthesized and incorporated into poly(vinyl chloride) (PVC) for the first time. The chemical structure of the ECODP was confirmed. The plasticizing effects of ECODP as a replacement for commercial plasticizer dioctyl phthalate (DOP) were investigated. The thermal stability and mechanical properties of PVC films before and after aging were investigated using thermogravimetric analysis (TGA), TGA-FTIR analysis, dynamic mechanical analysis (DMA), and tensile tests. The results indicated that PVC films plasticized with ECODP significantly improved thermal stability, compatibility, and flexibility. When DOP was substituted with ECODP completely, the initial decomposition temperature, 5, 10, 50, and 70% mass loss temperatures (T i , T 5 , T 10 , T 50 , and T 70 ) increased by 24.7, 38.9, 32.0, 30.3, and 102.7 C, respectively. The functional mechanism of the ECODP as a thermal stabilizing plasticizer and the plasticization mechanism of PVC composites were also investigated.

“…However, compared with film F0, the films modified by 12 phr and 40 phr EGESOFa had maximum increase of 23.9 and 20.2°C in T 10 and T 50 , respectively. It mainly due to the multi‐epoxy groups of EGESOFa which can scavenge for HCl and delay the degradation process .…”

A novel environmental soybean oil‐based plasticizer, epoxidized glycidyl ester of soybean oil fatty acids (EGESOFa), was synthesized and characterized by Fourier transform infrared (FTIR), 1H‐nuclear magnetic resonance (1H‐NMR), and 13C‐nuclear magnetic resonance (13C‐NMR). Effects of EGESOFa substitution of commercial plasticizer dioctyl phthalate (DOP) in poly(vinyl chloride) (PVC) films were studied. Dynamic mechanical property, thermal stability and mechanical properties of PVC films plasticized with different content of EGESOFa were investigated with dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and tensile and hardness tests. The results indicated that soybean oil‐based plasticizer could significantly increase plasticizing effect and improve thermal stability of PVC blends when partially of completely replaced DOP. Furthermore, EGESOFa could endow PVC resin with well‐balanced properties of flexibility, strength, and hardness. Surface characterization of films and the possible interaction between plasticizers and PVC molecular were also investigated. This soybean oil‐based alternative plasticizer has the potential to be a main or secondary plasticizer in food packing, children toys, medical devices, and other environmental plastic materials. Practical applications: An efficient alternative plasticizer was obtained in this study. The addition of EGESOFa to the PVC blends could be a potential application to manufacture high‐performance PVC products for the markets with high safety, health, and environmental demands, which are currently restricted to the petroleum‐based phthalates. This could be also a new way of soybean oil for industrial uses. A novel soybean oil‐based alternative plasticizer, epoxidized glycidyl ester of soybean oil fatty acids (EGESOFa), is successfully prepared and applied as a main or secondary plasticizer for poly(vinyl chloride).
