| Abstract: | The hyperbranched polyurethane water dispersion is prepared by grafting the polyurethane prepolymer to the hyperbranched polyester with dipentaerythritol as core and dimethylol propionic acid as monomer.The product is characterized and analyzed by IR,SEM and metric method.It appears that the particle diameter of the water dispersion is about 100 nm,and the hyperbranched polyurethane shows good dispersibility and stability in water;meanwhile,the resin shows good film-forming properties,water resistance and physical properties. |
