摘　　要：采用稳态剪切实验和动态剪切实验 ,研究了聚合物的摩尔质量及其溶液的质量浓度对于溶液粘弹性的影响 .结果表明 ,聚合物的摩尔质量越大 ,溶液的质量浓度越高 ,动态曲线中相应的储存模量和损耗模量也增加 ,溶液的松弛时间也越长 ;稳态剪切曲线中 ,溶液的第 1法向应力差随剪切速率的增加而增大 ;在低频率 (或低剪切速率 )下 ,动态剪切测量的复合粘度与稳态剪切测量的剪切粘度是相等的 .Through the steady and dynamic shear experiment, the effect of molar mass and mass concentration of polymer solution on its viscoelasticity is studied. It indicates that the more the molar mass of polymer solution and the higher the mass concentration, the greater the loss modulus and storage modulus of solution, the longer the relaxation time at dynamics experiment curves, the first normal force difference of polymer solution increases with the increase in shear rate at steady experiment curves. The composite viscosity at the condition of dynamic shear test is consistent with shear viscosity at steady shear test at the low shear rate or low frequency.
