We revisit the nonuniversal aspect of polymer dynamics by considering both new and existing data on the zero-shear viscosity and linear viscoelastic response of various polymers, each with a wide range of molecular weights. Analysis of the zero-shear

We found that the sizes of poly(acrylic acid) microgels in solution were high enough to be retained by rock matrix. To overcome this problem, we varied the mixing period and mixing rate with and without heat, added NaOH followed by HCl, injected the
