摘要
利用毛细管流变仪对不同配比的ＰＥＴ／ＰＢＴ共混体系的流变性能进行了研究。结果表明，ＰＥＴ／ＰＢＴ共混体系的表观粘度和结构粘度指数随组分的改变相应地出现了最小值，而非牛顿指数则出现了最大值，ＰＢＴ含量在１０％～２０％时。
In this work the rheological property of PET/PBT blend in different ratio has been investigated by means of capillary rheometer. The results show that the apparent viscosity and the structural viscosity index of the blends appear the minimum value with the content of PBT changing accordingly. Meanwhile the nonNewton index appears the maximum value. While the content of PBT changes from 10 to 20%, the flowactivation energy varies sharply.
