New soy-based polyols have been synthesized based on enzymatic conversions and alcohol moieties attached to a bodied soybean oil. Rigid, flexible, and elastomer polyols have been synthesized and reacted to from urethanes with a range of properties. Enzymatic modification was proven effective as a means to reduce degradation associated with higher-temperature reaction. Enzymatic modification was also effective for improved reaction selectivity. Use of the bodied fatty acid backbone was effective to increase the functionality and/or hydroxyl equivalent molecular weight. This paper emphasizes the approaches and results from use of bodied oil as a backbone for alcohol moieties.
