When shearing polymer melts and highly concentrated solutions of chemically uncrosslinked polymers, shear-thickening flow behavior may occur due to mechanical entanglements between the molecule chains, particularly if they are branched and therefore often relatively inflexible. The higher the shear load (shear rate or shear stress, respectively), the more the molecule chains may prevent relative motion between neighbored molecules.
