摘　　要：采用旋转流变仪研究了尼龙6/POE/EVOH共混物的流变行为。流变曲线结果分析表明:尼龙6/POE/EVOH共混物为假塑性流体,呈现出切力变稀的现象;EVOH的加入增大了尼龙6/POE/EVOH共混物的储能模量、损耗模量和复数黏度;用Han方法看出共混物没有发生相分离。时间扫描发现,时间对共混物的性能有一定的影响。The rheological behaviors of polyamide 6/POE/EVOH blends were studied by using rotational rheometer. The analysis results of the rotational rheological curves showed that polyamide 6/POE/EVOH blends were pseudo plastic fluid, and all specimens exhibited shear thinning behavior. The storage modulus,loss modulus and the complex viscosity of polyamide 6/ POE/EVOH blends were increased after the incorporation of EVOH. The blends were not phase separation did not occur as demonstrated by the analysis of the Han method. The results of time scanning revealed that time had effect to some extent on the properties of the blends.
