摘要
采用熔融共混法制备了聚酰胺6/乙烯-1-辛烯共聚物/乙烯-乙烯醇共聚物(PA6/POE/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:PA6/POE/EVOH共混物为假塑性流体,呈现出切力变稀的现象;EVOH的加入增大了PA6/POE/EVOH共混物的表观黏度和黏流活化能,说明共混物对温度的依赖性较强。
The PA6/POE/EVOH blends were prepared by melt blending.The rheological behavior of the blends was studied by capillary rheometer.The results show that PA6/POE/EVOH blends are pseudo plastic fluid and exhibit shear thinning behavior;the apparent viscosity and viscous activation energy of PA6/POE/EVOH blends increase with the addition of EVOH,which prove that the blends are temperature-sensitive.
