Technical Abstract: Ring-opening polymerization of epoxidized soybean oil (ESO) catalyzed by the super acid, fluroantimonic acid hexahydrate (HSbF6-6H2O), in ethyl acetate was conducted. The resulting polymers, SA-RPESO, were characterized using infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis (TGA), 1H-NMR, 13C-NMR, solid state 13C-NMR, and gel permeation chromatography (GPC). The results indicated that glass transition temperatures of SA-RPESO polymers ranged from -15°C to -21°C. TGA results showed they were thermally stable at temperatures up to 200°C. Decomposition of the polymers was found to occur at temperatures greater than 350°C. GPC results indicated the extracted soluble substances from SA-RPESO polymers were oligomers of ESO.
