| 摘 要： | 采用聚己二酸乙二醇丙二醇酯（PEPA）和4，4’-二苯基甲烷二异氰酸酯（MDI）为原料合成了聚氨酯预聚体，在预聚体固化剂中掺入环氧树脂，制备了环氧树脂改性MDI型聚氨酯弹性体，并对弹性体的结构和性能进行表征。结果表明，环氧树脂改性MDI型聚氨酯弹性体中存在嗯唑烷酮结构，提高了弹性体的热分解温度和耐热性能，但弹性体的动态性能变差，微相分离程度变弱。

| Abstract: | Polyurethane prepolymer was synthesized using PEPA and MDI. Epoxy resin was added in the pre- polymer during the solidifying process, then the polyurethane elastomer of epoxy-modified based on MDI was pre- pared. Elastomer structure and performance was characterizated. It indicated that the oxazolidinone was found in the modified polyurethane elastomer. The decomposition temperature and heat-resistance property of polyurethane e- lastomer was improved, but the dynamic property and microphase separation were decreased. |
