| Abstract: | The polyether-based polyurethane elastomers were synthesized by quasi-prepolymer method. The time and temperature of prepolymerization reaction were examined and the appropriate reaction qualification were ascertained ; The effects of moisture content, the mass ratio of hard segment and soft segment, molecular weight of polyethylene glycol, post ageing time on polyurethane elastomers performances were particularly discussed. |
