Interpretive Summary: In this research, we developed a cardanol derivative from cashew nut products and used it as a plasticizer in polyvinylchloride (PVC) films. It showed that this novel derivative improved the mechanical and processing properties of PVC film. It will be a promising biobased plasticizer.

Technical Abstract: A novel plasticizer derived from cardanol, epoxied cardanol glycidyl ether (ECGE), was synthesized and characterized by 1H-NMR and 13C-NMR. Effects of the ECGE combined with dioctyl phthalate (DOP), a commercial plasticizer, in soft poly(vinyl chloride) (PVC) films were studied. Dynamic mechanical analysis (DMA) was utilized to investigate the thermal properties of the plasticized PVC films and indicated a decrease in tan delta values and an increase in damping capability with small amounts of the ECGE. Mechanical properties of PVC films showed both tensile strength and percent elongation increased with increasing the ECGE content. Thermogravimetric analysis (TGA) was performed to characterize the thermal stabilities of the plasticized samples and showed the stability of films increased with increasing the content of the 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 and suggested the ECGE has similar or higher stability in those properties than that of DOP. FT-IR analysis for films also revealed that the ECGE interacted with PVC. Due to its inherent chemical backbone and the modified epoxy groups, the ECGE properly balanced the properties and improved the performance of PVC films compared with the neat DOP plasticizer.
