用不同的方法研究了尼龙6、尼龙6，6、尼龙6，10和尼龙11的熔体流变性能。人们已经发现，他们的行为是非常相似的，几乎牛顿的流动曲线和弹性和不稳定性。在高剪切速率下，两种试样的粘流活化能接近，但差别较大。这种材料的临界剪切应力与其他已知的聚合物进行了比较。
The melt rheology of nylon-6, nylon-6,6, nylon-6,10 and nylon-11, has been investigated by different techniques. It has been found that their behaviour is quite similar and almost Newtonian regarding both the flow curves and the elastic and instability properties. The samples show rather different viscous flow activation energies, although their values approach each other at high shear rate. The critical shear stresses of such materials are compared with those of other known polymers.
