| Abstract: | The polyurethane elastomer was prepared by the method of prepolymer based on polycaprolactone(Mn=1000,Mn=2000),diisocyanate and chain extender.The effect of different free ω(-NCO%),diisocyanate,chain extender and extender chain coefficient on the properties of polyurethane elastomer was studied.The results showed that polyurethane elastomer had better mechanical properties base on CP-20/TDI-100/MOCA and CP-20/MDI-100/BDO system. |
