Abstract: Cardanol-based polyol was prepared via the ring-open reaction between methanol and epoxidized tri(2-cardanoxyethyl) citrate,and its structural was confirmed by proton nuclear magnetic resonance (1H-NMR).Bio-based thermosets were then formulated using cardanol-based polyol and commercial isocyanate (hexamethylene diisocyanate (HDI,isophorone disiocyanate (IPDI),etc.) as the raw materials.The property of polyurethane was studied through dynamic thermal mechanical analysis (DMTA),thermogravimetric analysis (TGA) and tensile testing.The results revealed that the glass transition temperature of polyurethane was 43℃,The tensile strength was 940MPa.They possessed a good combination of high bio-based content and overall properties.
