The results showed that the m-PUE had better heat-resistant properties, lower glass transition temperature, higher thermal decomposition temperature and better damping property. The internal friction peak was changed from 10 ℃ to -10 ℃, while the tan δ was changed from 0.28 to 0.46. The hardness, tensile strength and tear strength of m-PUE decreased with the increase of the THEIC content. However, the swelling ratio of PUE was increased meaning a deteriorated solvent resistance property.

结果表明，引入IS环后，PUE的耐热性能有提高；IS改性的PUE的内耗峰比未改性的窄，峰位由10℃移到-10℃，且内耗峰值增大（tanδ由0.28增大到0.46），玻璃化温度降低，而阻尼性能得到提高；引入IS环的PUE的硬度和其它力学性能比未改性的PUE有所降低；随着固化剂中THEIC用量的增加，PUE的溶胀率增大，即IS改性PUE的耐溶剂性变差。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
