| Abstract: | Anionic polyether waterborne polyurethane in fabric-treating was synthesized by prepolymerization and closed end.The influence of mole ratio of NCO/OH,the 2,2-dimethylol propionic acid content(DMPA%) on the property of waterborne polyurethane emulision was discussed.The experiment result showed that the polyether waterborne polyurethane emulsion and its film have good property when synthesized under following conditions:the mole ratio of initial NCO/OH=3.0,the 2,2-dimethylol propionic acid content(DMPA%)6%. |
