Volatile by‐products during heat polymerization of soybean oil at 330°C were analyzed using GC‐MS and NMR. Color and viscosity changes were monitored for the heat‐polymerized soybean oil and the by‐products. About 90% (w/w) of the by‐products were decanoic, palmitic, linoleic, oleic, and stearic acids and cis ‐9‐tricosene. The by‐products also contained small amounts of 3‐eicosene, 9,17‐octadecadienal, and cyclotetracosene. The weight percentage of decanoic acid increased with reaction time, whereas those of other components showed no trends.
