采用毛细管流变仪研究了日本聚苯硫醚（PPS）树脂的流变性能。结果表明：随着剪切速率的增加,PPS的表观粘度降低;当温度升高时,PPS的表观粘度也降低;剪切速率越高,温度对剪切速率的影响越小;随着温度的增加,非牛顿指数增加且趋近于1,PPS熔体为假塑性流体;PPS的粘流活化能随着温度的增加而减小;此外,随着温度的增加,结构粘度指数减小。

Using capillary rheometer to study the rheological properties of Japanese PPS resins,experiments show that with the increase of shear rate,apparent viscosity of PPS resin decreased.And the higher the shear rate,the lower the impact of temperature on the apparent viscosity.As the temperature increased,Non-Newtonian index increased and tended to 1,PPS melt is pseudo plastic fluid.The activation energy of viscous flow of PPS decreased with the increase of the temperature.In addition,with the increase of temperature,the structural viscosity index decreased.
