Soybean oil, as an abundant renewable natural source, was subject to heat-bodying at 330°C via Diels-Alder Reaction mechanism for different times to obtain a series of Heat-Bodied Soybean Oils (HBSO) with different weight-average molecular weights tested by Gel Permeation Chromatography. Ozonolysis was then applied to HBSOs to obtain polyols by cleaving carbon-carbon double bonds. FTIR, NMR results proved the success of the synthesis route. DSC was used to investigate Tg of polyols, and viscosities were tested to determine the processing method for polyurethane production in the future work.
