| Abstract: | Aqueous polyurethane dispersion was synthesized by the reaction of toluene diisocyanate(TDI) with polyester glycol (T1136) and dimethylolpropionic acid(DMPA). The effects of the preparation technique, the reaction temperature and time on the properties of aqueous polyurethane dispersion were investigated. The results showed that the waterborne polyurethane has good storage stability and mechanical properties. The synthetic method was proved feasible and its process parameters such as the reaction temperature and time were obtained. |
