Technical Abstract: Ring opening polymerization of epoxidized soybean oil (ESO) initiated by boron trifluoride diethyl etherate in methylene chloride was conducted in an effort to develop useful biodegradable polymers. The resulting polymers (PESO) were characterized using Infrared (IR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), 1H NMR, C NMR, solid state C NMR and gel permeation chromatography (GPC). The results indicate that PESO materials are highly crosslinked polymers. They have glass transition temperatures ranging from -16°C to -48°C. TGA results shows the PESO polymers are thermally stable at temperatures up to 220°C. Decomposition temperature is found mainly after 340°C.
