摘要
利用Instron 3211毛细管挤出流变仪,对PBT/EVA共混体系的流变性质进行了考察。结果发现,即PBT/EVA共混系的流动行为接近牛顿/粘弹型流体。该结果对深入了解PBT/EVA共混行为有较大裨益。
In the paper, rheological properties of PBT/EVA were discussed by using of Instron 3211 Capillary Extruding Rheometer. It's very interesting that PBT/EVA blends are more or less Newtonian and viscoelastic fluids.
