| 中文摘要: |
| 采用预聚法制备聚醚型聚氨酯微孔弹性体。试验表明，影响其力学性能的主要因素有：二苯基亚甲基二异氰酸酯(MDI)的改性方法，扩链剂、交联剂的品种和用量，异氰酸酯指数。 |
| 英文摘要: |
| A cellular Polyether urethane elastomer was prepared with prepolymerization.The experimental results showed that the main factors which affected the mechanical properties of the material were the modifying method of MDI，the types and the levels of chain extenders and cross-linkers，and the number of NCO. |
