Moreover, unlike biopolymers, viscoelastic synthetic polymers possessing a flexible, random-coil conformation may obtain dilatant behavior in porous media where their apparent viscosities increase several folds with shear rate ( Wang et al ., 2008 ). Because of these viscoelastic properties, synthetic...
