Soybean oil is beneficial to improve the compatibility between polylactide (PLA) and succinylated lignin (SAL), which leads to the preparation of a host of biobased composites containing PLA, SAL, and epoxidized soybean oil (ESO). The introduction of SAL and ESO enables the relatively homogeneous morphology and slightly better miscibility obtained from triply PLA/SAL/ESO composites after dynamic vulcanization compared with unmodified PLA. The rigidity of the composites is found to decline gradually due to the addition of flexible molecular chains. According to the reaction between SAL and ESO, the Tg of PLA/SAL/ESO composites is susceptible to the movement of flexible molecular chains. The rheological behaviors of PLA/SAL/ESO under different conditions, i.e., temperature and frequency, exhibit a competition between viscidity and elasticity. The thermal stability of the composites displays a slight decrease due to the degradation of SAL and then the deterioration of ESO. The elongation at break and notched impact strength of the composites with augmentation of ESO increase by 12% and 0.5 kJ/m2, respectively. The triply biobased PLA/SAL/ESO composite is thus deemed as a bio-renewable and environmentally friendly product that may find vast applications.

Abstract In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester(ELCE) from cardanol and linoleic acid. Its chemical structure was characterized with FT-IR and 1H NMR. Polyvinyl chloride(PVC) blends plasticized with ELCE were prepared via thermoplastic blending with torque rheometer. The performance including torque, mechanical property, thermal stability, plasticizing property and migration resistance of plasticized PVC blends were investigated and compared with plasticized PVC blends with commercial plasticizer dioctyl phthalate(DOP). The results showed that ELCE improved thermal stability of PVC blends. ELCE played more excellent plasticizing effect on PVC blends than DOP. The better solvent extraction resistance and volatile resistance of ELCE make it impossible to completely replace DOP in PVC products.

Rigid Foam

A novel rigid polyurethane foam was prepared by using epoxidized soybean oil (ESBO) instead of 50% of petrochemical polyol-835 in the B-side of foam formulation. Although there are no significant variations in density and compressive strength of ESBO-based rigid foam compared with petrochemical-based rigid foam, better thermal stability and higher melting point (of polyether section) were attained and proved by TGA, DTG and DSC analysis. Presumably, the improved characterizations could be originated from the long carbon chain of ESBO and especially the oxazolidone structure as indicated in FTIR spectrum.

Thermal Stability Of

Frying accelerates oil deterioration through several chemical reactions, particularly lipid oxidation. Soybean oil (SBO), the polyunsaturated fatty acid (PUFA) rich oil, is prone to thermal degradation. Nevertheless, tea seed oil (TSO), mainly consisting of monounsaturated fatty acids (MUFA), is quite stable. This work aimed to elucidate thermal stability of SBO as affected by TSO blending at varying volume ratios. After frying for several repeated cycles, SBO/TSO blends with the ratios of 70:30, 60:40 and 50:50 showed lower total oxidative degree than SBO alone. FTIR spectra suggested less cis C=C deformation of the SBO blended with TSO, and the 60:40 SBO/TSO blend contained the lowest secondary oxidation products. Along frying, less change in viscosity (color) was found for the 60:40 and 50:50 (60:40) SBO/TSO blends. Improved thermal stability of the blended oils was expected due to the decrease in PUFA and increase in phenolic content, and this study suggested that the 60:40 SBO/TSO blend showed the highest stability.
