| 摘 要： | 采用毛细管流交仪测定了ＰＢＴ／ＰＣ共混物的表观粘度、剪切应力，观察了不同共混物组成和不同温度下共混物的流变行为，并借助扫描电镜对共混物和微观形态结构进行分析。结果表明：ＰＢＴ／ＰＣ熔体共混物的流变行为接近假塑性流体．温度对共混物的流变行为影响很大，共混物的熔体粘度在ＰＢＴ／ＰＣ为９０／１０和６０／４０时呈双极值．共混物为两相结构，ＰＣ含量为４－５０％时呈两互锁结构。

| Abstract: | An experimental investigation of the rheological properties and microstructure on PBT/ PC blends is studied. The viscosities of blends melts appear two extreme values at PC content of 10 and 40 percent, respectively. With the aid of scanning electron microscopy, the microstructure of blends has interpenetrating networks structure at IC content of 40 to 50 percent. |
