采用Instron-3211型毛细管流变仪对两种牌号的改性聚苯醚材料进行了流变性能测试;以幂率方程为基础,根据测试数据,拟合了熔体黏度与温度、剪切速率之间的定量经验关系式。将这个关系初步用于所述两种改性聚苯醚树脂的共挤出工艺制定中。
The rheological properties of two grades of modified polyphenylene ether were tested by Instron-3211 capillary rheometer. Based on the power rate equation, the viscosity and temperature of melt, the shear rate The quantitative empirical relationship between. This relationship is initially used in the formulation of the coextrusion process of the two modified polyphenylene ether resins.
