摘　　要：采用熔融共混法制备了PP/POE-g-MAH/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/POE-g-MAH/EVOH共混物为假塑性流体,其表观黏度随着EVOH含量的增加先升高后降低,当EVOH含量为20%时,表观黏度达到最大值。EVOH的加入增大了PP/POE-g-MAH/EVOH共混物的黏流活化能,说明共混物对温度的敏感性较强。The PP/POE-g-MAH/EVOH blends were prepared by melt blending.The rheological behavior of the blends was studied by capillary rheometer.The results show that： PP/POE-g-MAH/EVOH blends are pseudo plastic fluid.The apparent viscosity initially increases and then decreases with the increasing of the EVOH,and reaches to the maximum value when the content of EVOH is 20%.The viscous activation energy of PP/POE-g-MAH/EVOH blends increase with the addition of EVOH,which proves that the blends are temperature-sensitive.
