N2 - A waterborne polyurethane (WPU) dispersoid was synthesized through the prepolymer method using aliphatic isocyanates [namely isophorone diisocyanate(IPDI), hexamethylene diisocyanate(HDI)] and self-made polyester polyol as main raw materials. The effects of HDI/IPDI ratio on properties of waterborne polyurethane were discussed. The FTIR results confirmed the successful synthesis of WPU. As the molar ratio of HDI/IPDI increased, the properties (including elongation at break, solvent resistance, viscosity and thermal stability) increased, while the tensile strength and the average particle size decreased. The stable WPU with light blue and translucent were obtained when the HDI/ IPDI ratio was 1.5:1.
