| 摘 要： | 采用熔融共混法制备了聚丙烯／乙烯-乙烯醇共聚物（PP／EVOH）共混物，利用毛细管流变仪对共混物的流变行为进行了研究。结果表明：PP／EVOH共混物为假塑性流体，呈现出切力变稀的现象。马来酸酐接枝乙烯-辛烯共聚物（POE-g-MAH）的加入增大了PP／EVOH共混物的粘流活化能，说明共混物对温度的敏感性较强。

| Abstract: | The polypropylene/ethylene-sodium acrylate vinyl alcohol copolymer blends were prepared by melt blending. The rheological behavior of the blends was studied by capillary rheometer. The results showed that PP/ /EVOH blends are pseudo plastic fluid and all specimens exhibit shear thinning behavior. The viscous activation energy of PP/EVOH blends increased with the addition of POE-g-MAH, which proved that the blends are temperature-sensitive. |
