| 摘 要： | 研究了加工温度、辛烯含量和炭黑填充量对用茂金属催化剂合成的聚烯烃弹性体（ Ｐ Ｏ Ｅｓ） 流变性能的影响。结果表明， Ｐ Ｏ Ｅｓ 的流变指数小于１ ，属于切力变稀的假塑性流体，提高剪切速率，切敏性增强。 Ｐ Ｏ Ｅｓ 的粘度对温度变化不敏感，但随着剪切速率增加，粘度显著下降，表现出良好的切敏性。辛烯含量高时，切敏性强。

| Abstract: | Influences of the temperature, octene content and carbon black reinforcer on rheology behavior of polyolefin elastomers(POEs) produced using metallocene catalyst were investigated. The results showed that rheology index of POEs was smaller than 1, POEs was a kind of pseudoplastic fluid. The shear sensitivity increased as shear rate enhanced.The temperature had little effect on the viscosity of POEs,however,the viscosity decreased drastically as shear rate increased.POEs had good shear sensitivity.POEs with higher octene content had better shear sensitivity,with lower octene content had worse shear sensitivity. |
