The undecylenate based diol (UAD) has been synthesized from undecylenate by esterification and thiol-ene click reaction sequently, and then it was used as a diol to prepare bio-based waterborne polyurethane (WPU) reacting with isophorone diisocyanate (IPDI) and castor oil-based carboxyl hydrophilic chain extender. The structure of undecylenate based diol was verified by hydrogen proton nuclear magnetic resonance (1H NMR). Fourier transform infrared spectroscopy (FT-IR) was used to characterize the structure of WPU film. Furthermore, particle size and viscosity were used to character apparent properties of the bio-based waterborne polyurethane dispersion. The result shows that: bio-based waterborne polyurethane dispersion is transparent and very stable under room temperature. This work provides a simple and efficient method for the preparation of fatty acids based polyols and bio-based waterborne polyurethanes.
