Interpretive Summary:

Technical Abstract: Soybean oil polymers with lower molecular weight prepared in supercritical carbon dioxide (scCO2) by cationic polymerization were investigated for their applications as lubricants and hydraulic fluids. The low-temperature properties were studied by measuring their cloud and pour points; while thermo-oxidative stability of oligomeric soybean oil was studied using pressurized differential scanning calorimetry. Results show that increasing viscosity of soybean oil results in lower oxidation stability and increased pour and cloud points. These high viscosity soybean oils are desired in formulations of biobased gear oils and greases.
