| Abstract: | The RIM polyurethane elastomer was prepared by means of quasi-prepolymer process, with L-MDI, DMTDA.PPO as materials. The key affecting factors, such as synthesis method, variety of chain extender, hard segment content, isocyanate index, catalyst concentration , postcuring time and temperatuare of row material,on mechanical properties of RIM elastomer were discussed. The result indicated that the RIM elastomer of L-MDI/PPO/DMTDA by quasi-propolymer process had good technological properties. |
