The rheological results of the PP/MMT blend system indicated that the apparent viscosity of PP/MMT is higher than that of PP at lower shear rate and at higher shear rate the apparent viscosity of PP/MMT tends to be lower than that of PP.

• 对PP/MMT共混体系流变行为的研究结果表明，在低剪切速率下，PP/MMT共混体系的表观粘度均高于PP，在高剪切速率下，蒙脱土纳米分散的PP/MMT共混体系粘度有低于PP的趋势。 东华大学硕士论文聚丙烯/蒙脱土纳米复合材料的制备与结构性能研究
