| Abstract: | In this paper, stable polyester anionic waterborne polyurethane emulsion was prepared with JW2503, TDI and DMPA by acetone process. Effects of reaction temperature, reaction time, solvent, catalyst and its amount on prepolymerization was studied. Results showed that the most proper reaction temperature is about 65℃ and the reaction time is 2h, when the prepolymerization reaction conducted in acetone solvent in the presence of dibutyltin dilaurate as the catalyst. |
