It is used to quantitatively monitor the swelling of sodium polyacrylate and poly(acrylamide-sodium acrylate) gels in quasi two-dimensional constrained geometries. The experimentally obtained profiles for the Finger deformation tensor and the polymer concentration are compared with transient simulations of a model of transport in polyelectrolyte gels. }, year = {2000}, journal = {Aiche JournalAiche Journal}, volume = {46}, pages = {2128-2139}, month = {11/2000}, isbn = {0001-1541}, language = {English}, }
