| Abstract: | The polyurethane prepolymer was prepared with hexamethylene diisocyanate(HDI),polyester polyol and dimethylol propinic acid(DMPA).Then the prepolymer reacted with ethylenediamine extenders.The polyurethane emulsion was expanded in glass,drying at room temperature.Polyurethane(PU) cation-exchange membrane could be obtained.Glycollic acid was prepared via oxalic acid by PU cation-exchange membrane.By orthogonal experiments using current density,reaction time and temperature as three-factor two-level,the optim... |
