Abstract: 
										Polyol aqueous dispersions as the hydroxyl component of two-component waterborne polyurethane(2K-WPU) affect the structure and properties of 2K-WPU. The characteristic, preparation and modification of four kinds of polyol aqueous dispersions have been reviewed. Additionally, development trends of polyol aqueous dispersions have been described.
