| 摘 要： | 采用毛细管流变仪研究了生物降解共聚酯聚对苯二甲酸丁二醇／己二酸丁二醇／对苯二甲酸乙二醇／己二酸乙二醇共聚酯（PBATE）的流变性能．结果表明：PBATE共聚酯属于假塑性流体；在一定的剪切速率下，共聚酯PBATE的表观黏度随着温度的升高而下降；随着剪切速率的提高，PBATE共聚酯的表观黏度对剪切速率的依赖性较强，而对温度变化的敏感性却降低．

| Abstract: | The rheological properties of PBATE copolyester were studied with capillary rheometer. The result showed that PBATE copolyester was a typical pseudoplastic fluid; at a certain shear rate, the apparent viscosity of copolyester declined as the temperature increased; the dependence of the apparent viscosity on shear rate increased with the increasing of shear rate, whereas the temperature sensitivity decreased. |

| Keywords: | copolyester rheological properties： apparent viscosity non-Newton index viscous flow activationenergy |
