| Abstract: | A kind of waterborn polyurethane was synthesized by the reaction of disocyanate with polyethylene glycol at the presence of end capping reagent, the factors that affect the blocking reaction and prepolymerization reaction were investigated. Waterborn polyurethan can be synthesized at the presence of end capping reagent by taking sodium bisulfate as the accelerating a- gent. |
