| Abstract: | A polyurethane prepolymer was materials. According to measuring the content synthesized by using polyether polyol and isoeyanate as the raw of -NCO, the influences of reaction time and reaction temperature on the prepolymerization reaction were studied; the effects of the number of R n（ -NCO ）/n（ -OH ）], reaction time and temperature on the viscosity of the prepolymer were studied; and the influences of water content and the prepolymer storage time on the elastomer properties were explored. |
